The first rock concert I ever attended was Julian Lennon in Pittsburgh, 1985 I believe. We got seats in the sixth row, and one of my friends rushed to the front of the stage. Julian touched her hand at some point, and she went absolutely batshit insane. Among other things, she cut off her (long) fingernails and taped them into a photo album.
Anyway, I thought he was good but not that good, lol. I had the beginning of his song "On the Phone" on my answering machine for a bit but people complained it took too long before they could leave a message...
