yes !
i´ve been there. it was fantastic ! it rained since two days and it was raining during the gig.
it was all muddy . i think it was " woodstock mud " ha ha
but it was really fantastic , because all of the people were wet . so against the bad weather we all got drunk, to have fun.... it was extremely funny , ha ha .
i went back home by train totally muddy, wet , and drunken. ( well , i was a little younger that time )
it was late past midnight , when i came home. but my girlfriend waited for me and she was my nurse.... a great remembrance !
