I think LaurenceD's surmise that these records were sold at Nick's in NYC is probably dead on. Nick's was one of the first and longest-lasting of the hang-outs for the Dixieland crowd in NYC and especially favored the musicians who associated with Eddie Condon. With Nick's as a steady sales platform, you would think these records would be more common, but by comparison to similar records, like the Commodore label, they aren't. That leads me to suspect that the sales effort was of short duration or less than whole-heartedly supported by Rongetti and his staff, who were better occupied pushing booze and steaks. Possibly when the Mole band moved on, as they inevitably did at Nicks, the records went with them or when the personnel turned over to the point that the records no longer matched the band, which also happened frequently, they went into a back room and were forgotten. In any event, a complete album like this in good condition would be a nice find for a hot jazz fan.
Recorded March 2, 1945
From what I can gather, it looks like these albums were sold at Nick Rongetti's restaurant, where Miff's band performed regularly in 1945.
This album included an 8-page booklet which unfortunately is missing from my copy.
These tracks have been reissued on the Storyville label, but under Muggsy Spanier's name.
