Heard It On Luxi

By Paul McCartney and Wings.  Not a song ever intended for release - indeed, this was recorded in anticipation of the Band on the Run release, as a promo for Radio Luxembourg.

Denny Laine was on lead vocals, and Jimmy McCulloch was being tried out on lead guitar prior to joining the band.  A rarity I had to share.
