Speaking of the Ventures (who are still performing in Japan) I was amused to read that their drummer for "Walk Don't Run", Skip Moore, opted out of royalties from the recording, taking instead $25 for the session.
He later sued to collect royalties but failed because of his prior opt-out.
As to whom I would like to have over, here's a curve: Mary Margaret O'Hara, sister of Catherine and author of the amazing "Miss America" of 1988.
I gave a friend a copy of this performance I recorded off-air in 1988 and, to my amazement, he learned the whole performance exactly so he could duplicate it, body moves included! He was a very burly mountain man-type as well. It was hilarious!
