Coldplay thought it was about time to practice for their upcoming world tour and there's no better place to loosen the limbs than at Toronto's Kool Haus. After all their hits you'd think the band wouldn't have a problem playing their instruments, but apparently Chris Martin had some trouble figuring out his piano. Staring intently at the ivories, Martin could be overheard saying, "Damn! What bloody chord comes next?" He quickly figured out the A chord, cooed softly and everyone went nuts.
