"I Don't Want to Spoil the Party" is a song by The Beatles, written by John Lennon but credited to Lennon/McCartney.
The lyrics revisit Lennon's familiar themes of alienation and inner pain. In this song, he is at a party, waiting for his girl to show up. When it becomes clear that she has stood him up, he decides to go, rather than spoil the party for everyone else. Both the lyrics and melody share a melancholy sound…
I don't want to spoil the party so I'll go
I would hate my disappointment to show
There's nothing for me here so I will disappear
If she turns up while I'm gone please let me know
