I've seen quite a lot of footage of Wilson, Keppel and Betty, all of it intriguing. However, what's frustrating is that much of it (e.g. from YouTube) is unattributed or poorly reproduced. As a result, I'm trying to track down the original films that these clips appeared in.



I've already got copies of:

Variety Jubilee (1943)

Soft Lights and Sweet Music (1936)



However, I've had no luck so far with:

On the Air (1934)

In Town Tonight (1935)

Starlight Serenade (1944)



Any suggestions?
