Philadelphia is hosting a revisit of the Live AID concerts on July 2, 2005 as an aniversary party to bring global awareness of the "world 8" or something global leader conferences to be held later this summer. The concerts are free but you must get tickets. I'm sure you can pick them up on line. Also to inform you that if you are planning on staying at a hotel/motel etc. you had better book it now! I always go to the mountains for 4th weekend (wouldn't miss it!) but LIVE 8 sounds like a lot of fun!
