From Avalon Rolling Stones Offer text message contest
Through a text messaging program, fans who have already purchased a ticket to a Rolling Stones stadium concert will have the incredible chance to have their ticket exchanged & upgraded for one on stage.
The details are simple; concert goers are encouraged to bring their cell phones to the concert. Upon entering the venue, fans simply dial the reserved Rolling Stones short-code - 25852 and enter the word "Stones" (no additional charges, standard text messaging fee applies).
Winners will be chosen through a random draw and will be escorted On-Stage with up to one guest for an incredible concert event
