It is famously performed on The Ed Sullivan Show on September 17. In 1968, Buick offers the band $$$ to use the song in a car commercial; Morrison says no, threatening to have a Buick smashed with a sledgehammer on a TV show.
The show was cancelled too late to notify ticket-purchasers, who’d paid $20 for the weekend. (30 of 48 shows proposed that year are shut down by local opposition.)
Quite a similar thing happens in 2009 in the UK … a licensed festival running since 1994 is shut down.
