The Beatles succeeded for countless reasons, but their chemistry as four instrumentalists had a lot to do with it. For the vast majority of their songs, John Lennon, Paul McCartney, George Harrison, and Ringo Starr, with some production expertise from George Martin, made the magic in the studio without any outside help.
On occasion, they looked for guest performers who could augment their sound. Some of these folks were relatively unknown outside their fellow musicians, while others were stars in their own right. Here are five special guests who made a big difference on specific songs of the Fab Four. (Listed in chronological order.)
Alan Civil wasn’t the first guest to appear on a Beatles record, but his part on “For No One” made an impact that seemed to open the doors for the group to try it again. The song features McCartney singing about a guy whose relationship is crumbling before him, even though he’s too far in denial to see it. If McCartney’s vocals can’t get through to him, Civil’s lovely, melancholy horn part should do the trick. McCartney and Martin forced him to hit a high note that the instrument doesn’t normally reach, but Civil came through in spectacular fashion.
