Look at our heroes....
I seem to recall both Paul McCartney and Mick Jagger having some (ahem) minor legal problems with drugs....
I was at the Filmore East when Pete Townsend kicked an NYPD detective in the crotch as the guy came on stage to warn us that the building next door was on fire....
Jim Morrison exposed himself on stage....I saw Janis Joplin at Stony Brook, so drunk she could hardly stand up. Iggy Pop used to exonerate us to get out and burn down the establishment. James Brown used to cuff his old lady around like she was a punching bag. Ditto Sly Stone (who was usually too loaded to even show up for shows) and Ike Turner.
...but Lil' Wayne is a bad influence?
I'm an old, conservative, White Libertarian. Lil' Wayne and I exist in different universes. If Martians landed and changed Lil' Wayne into a large head of cabbage, I couldn't care less. I'd rather face root canal without Novacaine than listen to his music, but you know what?
I'm not so forgetful.....or so hypocritical that I'd ever say he should not be allowed to play.
Gee, aren't we ones to preach?
