Considered by Abbott & Costello fans to be their "lost" film, "It Ain't Hay" was never actually lost, but was unavailable for viewing for many years due to legal issues with the Damon Runyon estate. The film was televised decades ago (presumably before the legal issues arose) but was never released on video, and was not included in MCA/Universal's original DVD sets of A & C films that came out in 2004. In 2008 the rights issues were cleared and "It Ain't Hay" was included in the DVD release "Abbott and Costello": The Complete Universal Picture Collection."
During the "Glory Be" number you can see the cast march past a poster of Who Done It?, the previous Bud Abbott and Lou Costello movie, which was also directed by Erle C. Kenton.
