Glen Galyon, Curt Purnell, and Dick Wylder had already established themselves in 1936 as the Stardusters, and in 1939, were featured on NBC radio: The Vitalis Show, featuring George Jessel and his Celebrated Guests.

They were also featured in late 1939 and early 1940 with Frank Novak and his Music Creators on the Chiclets program heard over NBC.

May McKim — who had been a singer with an orchestra when she met Curt Purnell, married him on August 10, 1936, in Boston, and settled down to a non-professional home life — eventually joined the trio as a permanent member sometime around 1939.

And, they sang backup for Evelyn Knight's hit, A Little Bird Told Me, Decca Records, which became the subject of a landmark court case over covering.

Also † When Hutton left The Stardusters in 1944, Spivak brought in Gene Krupa's vocalist, Irene Daye, whom he later married.
