Truely classic! I especially love the bit at the end of the clip in which Shemp removes a guest's coat. I've actually seen this show in it's entirety. I own a VHS copy of this appearance. I believe, if memory serves me, that I bought it from a seller on Ebay. It's interesting all the stuff you can find on Ebay.
Thanks for posting the clip. I haven't watched my tape in some time, and it was fun to see the boys with Sinatra. Only the Stooges would have the courage to knock over the Chairman of the Board. Then again, it was cool seeing Frankie dish out a mean triple slap.
