Far out, thats a lovely story. We have neighbours that play music LOUD form time to time and its ok but sometimes it annoys me big time but they are always open to a polite "mate the kids are asleep and I cant, please turn it down".
By the way I had forgotten about Nanna and thanks now I cant forget the torment of my child as my parents played it.
As for a jamboree I am all for it in Vic or southern NSW somewhere like Wagga or a bit higher.
Cheers
James
