Three of the songs the Mamas and the Papas performed (My Heart Stood Still/Sing For Your Supper/Here in My Arms) appear on the DVD "California Dreamin': The Songs of the Mamas & the Papas," released March 29, 2005 by Universal Music. It also includes comments from Michelle & John Phillips regarding their involvement in the "Rodgers & Hart Today" show.
According to a studio technician The Mamas and the Papas were so stoned they had a hard time lip-synching their songs, especially Mama Cass.
Although no soundtrack album was issued The Mamas and the Papas recorded most of their songs, one of which, Glad to Be Unhappy, was their last Top 40 hit-it went to #26 in 1967. The Supremes recorded material for a 2-record set but only a single album was originally released, in June 1967, as The Supremes Sing Rodgers & Hart (Motown M-659/MS-659). In 1986 a CD was released with most of the extra material as The Rodgers & Hart Collection and in 2002 as The Supremes Sing Rodgers & Hart-The Complete Collection with, at least, one version of every Rodgers & Hart song the Supremes recorded at Motown.
