Now that I think of it, I knew that. But not about Tania Maria. I love one song of her that was on a Barclay release. Samba de Orly it's called and it's on an album called Via Brasil.
I love this set. And I was really surprised today (but knew it from before )when I discovered Ray Coniff playing trombone there. In a session by the Art Hodes Chicagoans.
On a Complete Django on Vogue set I have there's also (I think) part of the Duke with Django from their American tour of 1946 (I think). But I don't know how far that's identic to the Mosaic box, or if there's more there or on the set I have. I don't think the second applies.
