Pepper's Lonely Hearts Club Band . </P> <P> The song is sung by a young man to his lover, and is about his plans of their growing old together .

It was in the Beatles' setlist in their early days as a song to perform when their amplifiers broke down or the electricity went off . Both George Martin and Mark Lewisohn speculated that McCartney may have thought of the song when recording began for Sgt . Pepper in December 1966 because his father turned 64 earlier that year . </P> <P> Lennon said of the song, "Paul wrote it in the Cavern days . We just stuck a few more words on it like' grandchildren on your knee' and' Vera, Chuck and Dave'...this was just one that was quite a hit with us ."
