5 Seconds of SummerÂ (5SOS)Â surprised some lucky fans on Saturday by personally sellingÂ themÂ tickets to their upcoming show.
The Australian boy band is slated to play its first U.S. headlining concert this fall at The Forum in Inglewood, Calif., and fans were camped out overnight to score tickets.
They were thenÂ shocked to discoverÂ Luke HemmingsÂ and the guys actually manning the venueâs box office.
The group went on to treat fans to a special outdoor, acoustic performance of their hits âShe Looks So Perfectâ and âAmnesia,â and further surprised by bringing out a mariachi band and assorted goodies, in addition to holding an autograph signing.
âWe wanted yesterday to be epic for you guysâ¦ So we did this lol, cause whatâs more epic than this,âÂ 5SOS wrote on FacebookÂ Sunday morning.
They continued,Â âFor us this has been one of the biggest weeks of our lives. Thankyou to anyone who has the albumâ¦ You guys mean so much to us. Weâd still be practicing inAshtonâs garage if it wasnât for you. Thankyou thankyou thankyou !! X
Their self-titled debut album was released in the StatesÂ last Tuesday, and is expected to be number one on the Billboard chart.
