George Martin
When the Beatles began to break up in 1969, Martin felt the tension between the band's members. He was sometimes criticized for not being able to "fix things", or solve their problems. He began turning down sessions with the band. He let the recording engineer or the members themselves do his job. Martin returned to help make their last album (titled Abbey Road after the location of the studio), after all the Beatles promised to work with him "like the old days", and let Martin take charge of the sessions once more.
