Discussion: promise

I guess we have to ask. What was the promise?

He was signing autographs after a concert (not so well known back then), and I told him that my band did a cover of one of his songs. He thought that was cool and asked if I could send him a tape. I had never gotten around to it, and it had been bugging me all these years. I handed him a thumb drive last night, and he seemed quite pleased (and surprised), and said "I've been waiting for this!".

Ok that’s a good story.

Which song?

I'll Be Mellow When I'm Dead (original version and our version). Also, let it be noted for the record that the picture of us together was taken on February 30.
