Good ole "Broadway Melody"! In "Road Show" you discover Bessie Love laugh, clown, laughing because Charlie King, as a conceited singer, is in love with somebody else. There are dance numbers in Technicolor, back stage atmosphere and songs. Even the slapstick of Polly Moran and Marie Dressier and the humor of Jack Benny can't lift this out of the imitation class. All Talkie.
