Here are some answers pertaining to your post about the various Goldkette items:
1. Goldkette/Shield Piano Duet with Book-Cadillac Hotel Orchestra: When I was visiting New York City around Memorial Day, my wife and I stayed with Vince and Carol. I asked Vince about these recordings and if he knew anything about them. He didn't know anything about them, so he sent off an e-mail to his friend who could look into it for us. I don't think he's heard back yet because I haven't heard anything yet.
What is neat about this too is that Leroy Shield did a recording session with Paul Mertz on the same day in Chicago, 9/30/1926, after he did the session with Goldkette. Here is what I know from the Victor Recordings website:
BVE 36437 - Cover Me Up With Sunshine - Piano Duet w/Shield and Mertz
Take 4 is on Hold, Takes 1,2,3 and 5 were destroyed
BVE 36436 - I've Got A Girl - Piano Duet w/Shield and Goldkette
Takes 1 and 2 Destroyed, Take 3 Hold, Take 4 Master/destroyed, Take 5 Hold
It will be neat when Vince and I can find out if a master still exists! I would LOVE to hear Leroy Shield and Goldkette doing a piano duet, was well as Mertz and Shield!
2. Goldkette/Van Loan : I do know that Paul Van Loan did arranging for the Goldkette Orchestra in the late 20's and early 30's before Jean had to entirely break up the group due to the stock market crash. I have the interview with some of the Goldkette musicians when they were in California visiting with Jean and his wife, Lee, in 1939. Jean talks to Paul Van Loan on the interview, and says that he loved hearing him play saxophone in his orchestra. It's only a 2-3 minute conversation with Paul since there are other guys waiting to speak to Jean on tape.
3. Goldkette/Greta and Leroy : The story that Greta had told me about Leroy Shield was that she was dating him while they were in Chicago. She was with the Goldkette unit based out of the Drake Hotel. She told me that Leroy would come over to her place after he was done working in the Victor studios in Chicago, and he would walk in the door carrying a heap of records. She asked him, "Where did you get all those records?" He replied with an answer that went something like this: "We had a great day at the studio today, but we weren't going to use all the recordings that we made, so I thought I'd bring them over and give them to you." When I interviewed Greta, I asked her if she still had the recordings, which she replied with an answer of No. I did give her a 78 of the two recordings she made with the Goldkette Orchestra. Before the three ladies were "Jean Goldkette's Three Shades of Blue," they were know as Wynken, Blynken and Nod.
Hope that answers some of the questions pertaining to Goldkette and the names given in the post. We'll see you in a few weeks for the Bix Festival here in Davenport, which is going to be another fantastic festival!
