First Mystery Guest Johnny Mercer was able to stump the panelists.
In 1964, the high esteem in which Johnny Mercer was held as a lyricist may be noted by Ella Fitzgerald's tribute in her studio album 'Ella Fitzgerald Sings the Johnny Mercer Song Book'.
This broadcast aired after the iconic American TV moment 'Meet The Beatles (1964)', which was considered one of the highpoints of the "British Invasion" cultural phenomenon of the mid-1960s.
Johnny Mercer wrote the lyrics for the Broadway musical 'Foxy' that would premiere the following week at the Ziegfeld Theatre. The show was tailored specifically for the talents of Bert Lahr and ran for 72 performances until April 18, 1964.
