The Ed Sullivan Show's YouTube channel recently uploaded a video of the Band performing "Up on Cripple Creek" (dated 2 November 1969), and since there's a fairly clear albeit brief shot of Garth Hudson's Clavinet, I thought I would post it here.
The instrument is clearly an early model, either a Clavinet I or a Clavinet II. Normally, the name would be displayed on the panel beneath the keys (as seen with the Clavinet I here), but this has been removed, apparently for tuning purposes. According to this site, however, Hudson had a Clavinet II. As far as I can tell, the only difference between the Clavinet I and the Clavinet II is that the Clavinet I had built-in speakers but the Clavinet II didn't.
