Freecatcher readers, we’ve got a great contest opportunity for you here! First, go to your Facebook account and “Like” iTunes. That’s a pretty good bit of advice, anyway, as you’ll see frequent offers and useful advice on their wall posts. More specifically, though, today you can sign up to win some great concert prizes!

iTunes London Festival presents 31 nights of back-to-back live music – you could be one of three winners to bring a friend with you for five nights at a luxurious London hotel and tickets to three consecutive nights of live music! You have until June 30th to enter the drawing and winners will be announced between July 1st and 5th – oh, and be sure you have a passport ready, because London awaits!

London not your thing? How about the VANS Warped Tour 2010 brings some of the industry’s most popular punk rock bands to 35 U.S. cities. Five winners will be chosen to get a pair of tickets to the Vans show at the city of their choice – choose the city when you enter the contest, right there on the iTunes Facebook page!

Two great concert contests, and you’re welcome to enter them both – double your chances!
