Wikipedia notes that
Thelonious Monk’s 1948 composition, “Evidence”, was based on the chord progression of “Just You, Just Me”. Monk’s tune was originally called “Justice” (which sounds like “Just Us”, a reference to “Just You, Just Me”), then renamed “We Named It Justice”, and finally “Evidence”.  Both songs are included in Monk’s 1964 live album, Live at the It Club.

The Brox Sisters were a close harmony vocal group of three sisters. Born in Kentucky and Tennessee, they grew up in Edmonton, Alberta, Canada. Their real last name was Brock but they appeared on stage as the Brox Sisters. They rose to fame in the Music Box Revue which played at the New York Theater from 1921 to 1924.
[Ed. The theater was and is called The Music Box Theatre. It was built by by Irving Berlin and producer Sam H. Harris specifically to house Berlin’s Music Box Revues. I think what is meant here is that the Brox Sisters were in the Music Box Revue of 1921 and subsequent Music Box Revues until 1924. Redhotjazz.com and wiki each misname the theater in their profiles of the Brox Sisters.]
In 1925 and 1926 the sisters performed in the Broadway production of Cocoanuts with the Marx Brothers. In 1927 they appeared in the Ziegfeld Follies of 1927 at The New Amsterdam Theatre with Eddie Cantor. In 1929 they appeared in the film Hollywood Revue of 1929 performing the song “Singin’ In The Rain” with Cliff Edwards. In 1930 the sisters appeared in the film “King of Jazz” in 1930. They performed the song “A Bench in the Park” with Joe Venuti, Eddie Lang and the Rhythm Boys.

The youtube provider dates the recording 1955, but according to Judy Garland Database she only recorded the song in a studio once.
