When Will tells Lisa in the letter to turn on the music it is the same music that was used in the episodes Not I, Barbecue and Did The Earth Move For You.
Will schemes to get John Ridley bumped off the Tonight Show's venue. John Ridley is a story writer for The Fresh Prince of Bel Air.
After the scuffle in the bowling alley, Will and Lisa have this exchange:
Lisa: Will, I've been meaning to tell you that I'm a
Will: A what!? A Power Ranger!?
It is interesting to note that in the original pilot episode of Mighty Morphin' Power Rangers, the main characters actually fought off a few bullies in a bowling alley. The conflicts in both episodes started by a random male hitting on a female character (In Fresh Prince, Lisa; in Power Rangers, Kimberly). Another interesting fact is that the role of Trini, the Yellow Ranger, was played by Audrey DuBois, who bore a similar resemblance to Nia Long.
Phillip proposed to Vivian on Soul Train 25 years ago which be around 1969 but Soul Train began in 1971.
Don Cornelius played himself in this episode as the host of Soul Train. Except he left the show in 1993.
Title: Sooooooooul Train
The title is fashioned after the way the announcer introduces the beginning of each episode of Soul Train
Goof: There are not enough letters on the scrabble board for Philip to spell out his marriage proposal.
The live audience can be seen as well as the sets and stage crew as Carlton runs around frantically at the end.
The mask Jazz has on in the final scene actually looks nothing like Brad Garrett. This is clear if the 'unmasking' shot is played in slow motion.
Goof: In the last scene, it's obvious how they switched actors when the mob killer comes to the pool house looking for Will. When the killer first enters the pool house, the mob killer is so tall that his head almost reaches the basketball hoop mounted above the door. Then, after Will screams, we see that it's Jazz wearing a mask, but Jeff Townes isn't as tall as Brad Garet and he doesn't come nearly as close to the basketball hoop as was Brad did.
When Carlton says to his Philip "since when do they have high school reunions for their twenty second year?" meaning his high school reunion would have been in 1967 and since he was born in 1946 that would have made him 21 but he would have already finished high school and most likely college since he moved to Baltimore at age 16.
Goof: During the nursing home dream, old Will tells old Carlton "I ought to knock your teeth out" to which old Carlton replies "Go ahead; they're on a glass next to my bed," but Carlton's teeth a visible in his mouth during the scene.
Goof: Hilary records the television show using a video camera, but when a video camera gets near a monitor or television of any kind, interference lines are displayed across the screen. The playback from what Hilary recorded has no lines.
Anastasia Ali who plays Bashley is Tatyana Ali's younger sister who also was in the episode Someday your prince will be in effect as one of the trick or treaters.
Goof: After Ashley becomes a big-time diva, we see Will at the Peacock interviewing new talent for a replacement for Ashley with a sign that says, "Ashley Bank's Former Agent Seeking New Talent". It should say "Ashley Banks' Former Agent Seeking New Talent".
Goof: In the beginning scene, Uncle Phil tells Nicky to go use the restroom before they leave and Nicky goes, but towards the end of the scene Phil says that's everyone even though Nicky hasn't returned yet.
At the beginning of the episode Jazz asks if the mother is still the same and Will responds by saying of course. Just then a drastically aged Nicky walks in the room leaving Jazz with a confused look!
Ashley (singing):...that's gonna make you move and groove. Hey D.J. keep playin' that song all night. On and on and on.
The song that Ashley sings is Hey Mr. DJ by Zhane.
Since the previous season's finale was supposed to be the final episode, it left Will staying in Philadelphia. It was wrapped up in the opening scene when it was explained humorously that the show's title is not The Fresh Prince Of Philadelphia as the NBC executives threw Will in a van and drove him back to Bel Air.
The Fresh Prince of Bel-Air was canceled at the end of the fourth season when Will returned to Philadelphia because ratings had declined. The fifth and sixth seasons happened for a couple of reasons. First, both Will Smith and NBC received a large amount of mail begging them to keep the series on the air. Second, the NBC affiliates were repeating the old episodes and those repeats were getting high ratings. Most of the station managers were worried that with only 99 episodes audiences would soon tire of seeing the same old episodes over and over again so many of them offered to pay a much higher fee than usual for the rights to run the repeats if NBC would produce 50 more episodes.
