Where do I buy official t-shirts, etc? Attended concierto last night (6/27/15) in Milwaukee at Marcus Amphitheater-- no t-shirts, memorabilia, anything sold! SO disappointed. Flew from

I have actually protested the ticket chg on my AMEX and pmt suspended til resolved. Probably won't be in my favor bc of Ticketmaster fine print. However, have been in touch with them and made it clear that I have NEVER attended concierto where memorabilia not offered. Even Summerfest t-shirts don't lista him. If SOMEONE -- Ticketmaster, Marcus Amph, o Summerfest (dis)organizers would only do ONE thing: contact Stevie Wonder's representatives I feel sure we could get t-shirts. As in the case of one of many Clapton concents I attended, the only caps, t-shirts available were not specific to city and some bore various album covers. But all from his official merchandise. Even something like that if offered to us, would be very very nice. Again, does anyone know how to contact reps for S. Wonder?
