Big Bill Broonzy and Jazz Gillum

["MaryLarryCarleighReilly Pratt" <mlpratt@xxxxxxx>]

Lotsa chatter about Big Bill lately.  He's bonafied.  He's credited with
having penned Key to the Highway, an all time classic.  I thought I remember
some dispute between him and Jazz Gillum as to who actually wrote the tune.
Is there any evidence that Jazz may have actually written Key to the
Highway?

Best Regards to All,
