Yup, they're the funk rock band that formed in 1963 in Los Angeles.
It all depends! You have bands like the Red Hot Chili Peppers who, although have not reached the popularity of the Rolling Stones, have been around since 1983 themselves. Many bands reach a legacy and are able to continue playing for decades
I love rock and roll music.  Do you know much about the genre? It's a genre of popular music that came about in the United States around the late 40s/early 50s, from African American musical styles, like gospel, jump blues, jazz, boggie woogie, and with some country music thrown into the mix! So it has a lot of influences.  When was rock music the most popular? I'm unable to say but around the mid-1960s was when it turns to "the more encompassing international style" of rock music Is rock and roll still popular today? It's hard to say, have you heard of classic rock and roll though? It's played with 1 or 2 electric guitars, string or double bass or electric bass (after mid 1950s) and a drum kit. I think I have but more of the musicians than the genre itself. I think Rolling Stones might be one but I'm not sure who's part of the band. Have you heard of Mick Jagger? For their first stable line-up, he was the lead vocals. Oh I definitely know him, I totally mixed him up with another band though lol! I was thinking of Red Hot Chili Peppers for some reason lol! Do you know them?
