@8th-note , I recall my two older sisters listening to them (The Beatles and Dylan) when I was growing up. There was a pretty good age gap between them and me, and back then I didn’t have a real appreciation for music, however I did find a lot of what they listened to interesting, and I now credit their (my sisters) influence to be why I became a fan of Dylan as I grew older.
Speaking of offensive lyrics, I remember them playing a protest song quite loudly (my oldest sister’s bedroom had the "stereo" and it was down in the basement) and what I remember was "GIMME AN F!! [. . .] WHAT’S That SPELL!!" I remember that rather clearly. I think my oldest sister did that to piss my folks off. I also remember some interesting songs off of the Hair (was it a sound track?) album. The one I am thinking of at the moment was titled Sodomy. The line that got my attention back then was, ". . . masturbation can be fun . . .". I wouldn’t be surprised if the reason she played that was also to get on my folks ’nerves.
