This was originally released on a Royal Blue Columbia record, 2926-D, and spelled STOMPING AT THE SAVOY, with the band identified as CHICK WEBB'S SAVOY ORCHESTRA, and only '(Sampson)' as the sole composer credit.
What I have is a 1936 ARC Vocalion reissue, pressed from the original Columbia matrix W.152740-2, recorded 18 May 1934.
