Anything or group after “the day the music died” ain’t R’n’R. Bill Haley and the Comets, the black groups that were covered by Pat Boone and others, were the best.
Well, we all have our dates when “the music died”, that range between 1958, and, say, 1975, , but certainly, many of the pretentious and the inept (Chicago? Grand Funk Railroad? Pleeze!) listed above, have as much relation to rock’n’roll as Pat Boone, if not less.
