I dont recall which of the live club cds this is from, but Neil notices a space on the floor between the band and the audience and feels the need to go occupy it, which he does during one song.
Then he says that playing down there reminded him of when he was 15 yrs old and used to have parties. He thought playing guitar would get him some action with the girls, but instead, as he played music, the girl he liked would head off with some other guy. So, essentially, he was the mood music for THEIR romance.
Every time i hear this story, i think "Awwwww poor Neil!"
