Wow, that was great to hear, must have been great to play with Grappelli! I can only imagine... Well, it's my pleasure to meet you, I don't play bluegrass, at least not yet but am good friends with Don Stiernberg and Steven Briggs (bluenightrecords.com) who do. We used to play in Chicago. I also got to jam with Beppe Gambetta a couple of times, in any case, thanks so much for sharing those experiences with me, it was a thrill to listen to. Good luck with your upcoming shows and yes, we'll talk soon, ciao!
