Carmelo and the Boogie Ramblers posted a great video of Chuck Berry playing "Roll 'em Pete" on Soul Train on their facebook page. I couldn't find that one on youtube, but it got me to this beauty, by Berry's childhood hero Big Joe Turner. Pretty cool. And since it was cut in 1938, it shows the truth of Berry's frequent statement that "there's nothing new under the sun."
And if it works, here's a link to what the Boogie Ramblers posted-- a great version, with some fun questions and answers at the start. ("Roll 'em Pete" is the only Chuck Berry single I bought. I think it had "Bio" on the flip side. I bought it because it was the only way to hear the song, which didn't come out on the London Sessions album.)
