That brings back some memories. My old partner bought a '72 Mercedes 350SL from him, but he never mentioned the DiDia, that is way cool. I'm not sure if he had already sold it, that was about '83 when my partner bought the 350SL from him. My gut tells me he didn't make any money for a long, long time and was just selling stuff he had acquired to survive. He had some cool stuff, and he probably still gets residuals from his music. A really down to earth guy...but that DiDia is way cool!
