Tickets to already-sold-out music festival Glastonbury are up for grabs in a new on-pack text-to-win Tuborg promotion. Brand owner Carlsberg is giving away five pairs of tickets to the July event.

Consumers text a number printed on the limited-edition packs, which are available now. The offer, which also includes runner-up prizes such as Glastonbury 40th anniversary T-shirts, will run until the summer.
