Tommy Brown was my dad. I have a record of the band with Boots and Don which is a complete studio demonstration of their act with many songs like "Transistor Radio", "Sweet Little Sixteen", "Hungry for you babe", "Caravan", but the version of "In the Hall Of The Mountain King" is out of this world.it's some faster than this version , more organic and the standout is Don Adams' execution of the guitar sections. There's also a novelty Slavic sounding number with fast, tricky guitar passages where Adams really plays brilliantly. They really must have been something else live. Olivier Brown
