Here's another episode of a series of Dennis Day variety shows that I've not been able to dig up much info on.
In program 191, as broadcast on the Armed Forces Radio and Television Service, the guests are Vera Ellen and Johnny Mercer. Dennis sings "The Best Things in Life are Free" and Mercer sings his new song "Lonesome Polecat". The comedy sketch is "This is Your Past, Y'all!", the life story of Johnny Mercer. The date July 31, 1955 is stamped on the disc label, which may indicate when it was broadcast by a local AFRTS station.
The show was transferred from an original set of vinyl AFRS transcription discs.
