I’m with you, the Beatles are better than KISS musically.
No browbeating intended, no one needs to like the music of KISS, but you said Herr Eisen is “gross and creepy”, that didn’t strike me as a comment on his vocal, instrumental or songwriting capabilities.
Re the vid: If Paul had played a Fender P, he would have never developed that trademark “bopping around” with his Höffie which as an instrument never really sits still.
