When we snuck into the 1984 Frank Zappa concert on Winter Island, Salem MA we got front & center about 30' from the stage.
(Try sneaking onto an island without getting your feet wet. We did it.)
The guys next to us had made a DIY banner about 10 feet long attached to posts to hoist it but they were too pussy to hoist it.
It said "Frank, Shut Up And Play Your Guitar!"
Me & my friends commandeered it and hoisted it a few times but only a few because it was kind of obnoxious to ppl behind us.
Helluva show.
