I haven't been too many concerts since having kids.... I think the last one I went to was Gary Numan. As far as meeting bands, does having drinks with the members of the Knack count? It was the bassist's birthday when they played a club one night and during the show I happened to strike up a conversation with one his friends who'd come down (from L.A. to San Diego) to celebrate afterwards. We stayed after-hours while the club staff cleaned up around us.
That counts.
I had Get the Knack on 8 track.
