"This":http://mog.com/Walter_Weiss/blog_post/92704 post got me thinking about the places that bands don't want to, can't or aren't allowed play.How many countries are still in that situation?Is it local security officials, international record companies, promoters or the artists themselves who say no? And why?Or is it the case that most bands can tour everywhere, but we only hear about it when someone like Paul McCartney plays China or the Manic Street Preachers play Cuba?And why did Elvis Presley never play Ireland?!
