what’s your personal fav. peak RnR moment?
… rock and roll?
Ahh. That makes more sense. I was thinking “Rest & Relaxation”.
God forbid the OP avoid stupid acronyms and make their meaning clear to begin with.
John Lennon hanging out with the Rolling Stones for their Rock & Roll Circus gig/film.

Also, his apostrophe is backwards.

Here ya go
The Beatles’ first appearance on The Ed Sullivan Show, on February 9th, 1964. It was their first public performance in the U.S., it launched the British Invasion, and was the start of a course change in rock music in the U.S.
How have I made it this far in life and not seen or heard of this? 
Naw, Rock n Roll peaked a couple months earlier…
Elvis Costello & the Attractions playing “Radio, Radio” on Saturday Night Live. Story goes like this: the band was booked for the show and wanted to play that song (their current single), but the producers said “no way” because of course it’s a tirade against corporate media and so they understandably wanted none of that. They agreed to play “Less Than Zero” instead, which already was an old song. So the band enters the stage and begins playing “Less Than Zero”, but they stop after a few bars and launch into a stomping version of “Radio, Radio” with all the glee Costello could muster. Producers going nuts, and EC banned for American TV for years. One of the biggest fuck-yous to the suits in rock history, and isn’t that what rock’n’roll is all about?
