Speaking of Whiteman: a great duet by Trumbauer and Steve Brown.

When the Goldkette band disbanded in the Fall of 1927, Steve Brown joined the Whiteman organization. Bix and Tram followed a few weeks later.

On Jan 24, 1928, the Whiteman concert orchestra recorded the Rodgers and Hart tune My Heart Stood Still. This was issued on a 12-inch Victor disc, Vic 35883. 

A very interesting arangement by Bill Challis: first a slow, romantic section with a vocal by the Sweet Trio with Al Rinker added, then a hot section with a spectacular duet with Tram improvising a 32-bar solo and Brown slapping the bass.  Listen

We always think of Margulis as the perfect player, no errors. However, read what Don Rayno writes about this recording, "Challis originally intended for Margulis to play the entire eight-bar closing, but he fluffed the high F during rehearsals, prompting Whiteman to give the last four bars to Hazlett to play on his E-flat clarinet. Apparently, Whiteman changed his mind again when it came time to record the arrangement, for it is Rube Crozier who takes the ending on his flute, per Whiteman's red-pencil instructions on the score."

My Heart Stood Still is one of the songs in the production of A Connecticut Yankee, Vanderbilt Theater, 11/3/1927-10/27/1928. Another of the songs in the production was Thou Swell.
