His gag novelty song "My Ding A Ling" hit number one in the USA and the UK in 1972, definitely a "pop" hit in its time.
I was lucky to see the 1973 oldies movie "Let The Good Times Roll" which featured Chuck Berry, Bo Diddley, Little Richard, and other 50's greats, saw it on the big screen in a theater, too. For a long time this was a "lost" film because of its heavy use of split-screen that didn't work well when displayed on TV/VHS video. Chuck was in great form during the filming, and even jams for the first time ever with Bo Diddley at the end of his set.
There's a little bit of Berry in ya if you play guitar. And if you don't play, you still have been down Berry Lane. One of the most influential figures in rock. RIP Chuck, and thanks for all the music and memories.
