I got 19 right. Missed the Bob Dylan lyric. That was fun...and some of those things I didnt experience first hand, but later as reruns, etc. if you get my drift! LOL!
I only got the Bob Dylan one wrong, but I think he kept changing his tune, no pun intended, as he got older.
I'm not sure if I'm a boomer, either (1958). I guess it depends who you talk to.
