Harmonica in the Movies question

[IcemanLE@xxxxxxx]

I rented a movie called "Stormy Weather" starring an all black cast - Lena 
Horne, Bill Robinson, Cab Calloway, etc. Silly plot with some kick musical 
numbers and tap dancing.

The movie opens up with Bill Robinson teaching a group of children some tap 
steps on the porch of an old house. The background music is diatonic harmonica 
with a DeFord Bailey type style, very well done. Unfortunately, there is no 
credit for who the musician is.

Any ideas?
