Reinhart and Abrams were also joined by Memphis native Dee Dee Bridgewater, a Grammy-Award winning jazz singer who shared the stage with jazz legends Sonny Rollins and Dizzy Gillespie and collected a Tony Award for her portrayal of "Glinda The Good Witch" on Broadway in The Wiz. Bridgewater and Reinhart accompanied drummer Shannon Powell for a duet of "Hit The Road Jack," with Abrams adding vocals plucking away on an upright bass.

Both Idols dressed up for the occasion -- Reinhart in a floor-length gold colored gown and Abrams in a classic tuxedo.

In addition to "Hit The Road Jack," a duet included on Abrams' debut CD, Reinhart entertained with a bluesy and soulful take on the Billie Holiday classic, "God Bless the Child" (with Mayfield on trumpet; listen here) and the Johnny Mercer/Harold Arlen standard "Blues in the Night."

As for Abrams, his New York trip was especially productive. The multi-instrumentalist performed his single "Get Out" on VH-1's Big Morning Buzz Tuesday morning.
