The Ambassadors band had saxophonist & clarinet-player Ray Starita as leader, along with his brother Rudy on drums, vibes and xylophone.

When the band performed at The Ambassador Club, Conduit Street, London, the brass section was not usually present. Appearances at The Ambassador were between April 1928 & April 1930 and April 1931 & circa July 1932. From September 1932 to 1933 the Ambassador was dropped and the band were simply known as Rudy Starita and his Band.

On some recordings the band has been variously credited as:
Andre Astan And His Band [Sterno #986 & '4in1' #7]
The Rhythm Aces [Sterno #1007 or Redwing #1002]
Nat Starr And His Orchestra [Sterno #1010]
The Twelve Rhythm Monarchs [Sterno #1023 & '4in1' #6, #7 & #8]
Billy Seymour And The Boys [Sterno #1036]
Chick Hall And His Collegians [Redwing #1003 & #1004]

(There were three American-Italian Starita brothers; the eldest Rudy Starita, born in Naples, then in America [Renato] Ray Starita and Al Starita. Ray returned to America in 1932 and became an amusement park owner.)
