This is Ritchie on the 1959 Winter Dance Party. A couple of days before he died. Got a Strat, which, from what I understand, were not very popular at the time.
Waylon Jennings, on bass, looks on.
I am pretty sure this is the only known footage of RV playing the guitar. It looks like he does cut to a solo at the end. There is a few seconds of video at his farewell party playing a Start at home. He definitely played a strat on the Winter Dance Party Tour.
Try listening to Live at Pacoima Middle School. The albums 'B' side has a lot of takes of hiw different songs. You can hear Bob Keene in the background pushing RItchie to finish the songs. The raw sound of the guitar/band is pretty amazing
