A friend "loaned" his DVD to me, and sadly I cannot copy it, burt I did get to watch it a number of times.
There must be copies floating around. I think it was part of an Ed Sullivan show and I do know that some Sullivan show tapes are for sale. Perhaps some searching?
Technically Galli Galli was weak, but his brash, direct style, coupled with his wardrobe and "foreign" way made it really work.
He used corks instead of balls, cut short, so they wouldn't roll away.
His false transfer was crude, but hey, it got the money!
