Very interesting video here - I don't think I've ever seen live D+D from this timeframe.  I'm assuming this was the 1986 touring line-up - maybe?  Oh yeah - the sound is pretty horrible - which is a shame.  Will have to keep an eye out for another better version.

While I was looking into this - I came across a couple of D+D shots from the era - hmmmm.... Ricketts seems like the troubled one here...
