I've heard some tunes in recent years that were pretty close to that same idea. The idea was you turn on the radio and you want to hear some music and up comes a commercial.

I never bothered about keeping track.Every now and then someone records one of my songs, and I get credit for it.

I do some concerts. At the moment, I'm being helped a lot by a gig I play in London, which is Pizza Express.

I didn't feel anything [frustraiting]. I just kept working 110 or 120 nights a year.

I remember the first check I got from The Who's recording [of "Young Man Blues"]. I'd been getting checks for $10 and $15 and so forth, and this one was for a much larger amount than that. I thought it was a mistake.

I've been able to do pretty well. I don't work as many consecutive nights as I used to, but I'm still working over 100 nights a year, so that's good for me.

I'm happy whenever anybody does my material. I don't care what they do with it. I do what I want to with other people's songs.
