Does anyone remember the little handheld Casio Keyboard from the early 80's? It didn't really have proper keys, more like key 'pads' but, and here's the great thing, it had the exact rhythm from the 80's Trio hit record "Da Da Da"! Obviously they used one for recording. Instantly you were a pop sensation if you owned one of these. I wonder if any famous musicians 'cut their teeth' on one of these little beauties?
