This music is for the song Fit As a Fiddle (and Ready for Love). Lyrics by Arhtur Freed, music by Al Hoffman & Al Goodhart. On this song sheet it says "featured by Jeanie Lang" a singer from the 1930's. More famously, the song was performed by Gene Kelly and Donald O'Connor in the film Singin' in the Rain, the movie which featured songs by Freed.
Sheet shows some wear, tears on each side of the music. Has great illustration of a dancing Fiddle saying "Hey Nonny Nonny and a Hot-Cha-Cha".
