This is him at rehearsals in Dundee with local jazz enthusiast, Alf Anderson, who himself was a dance band drummer.
The Duke chatted away while knocking out a few tunes. He explained that the reason for him wearing 2 cashmere sweaters and an overcoat at the time was because the hall was so cold.
He then asked if Dundee made their own brand of whisky as he wanted to buy some to take back to his friends and surprise them with a new label!
Not sure if he ended up in a nearby off license!!
