Hot Chocolate - I Believe In Love

What a great tune by Hot Chocolate! I love how loud the hi-hats are in the mix. It reminds me of how loud the hi-hats are on the Blond album. I first saw this video courtesy of my friend Jessica. This comes from a series of VHS tapes called Music Unlimited that had all these music promos filmed in the early 70's of artists like The Equals, Tony Hazzard, Emitt Rhodes and The Sweet among others. Anybody know the history of these clips?
