The first Beatles song that Martin did not arrange was "She's Leaving Home" from Sgt. Peppers. As he had a prior engagement to produce a Cilla Black session, Paul McCartney contacted arranger Mike Leander to write the arrangement - reportedly hurting George, although he still produced the recording and conducted the orchestra. This trend continued as Martin was in great demand as an independent arranger/producer and The Beatles were less willing to be "led" as they had been in the past. By the time of The Beatles, they were left to produce an increasing number of tracks by themselves.
