We thought we'd end the first trio of Merthyr Rock videos with our only cover song of the weekend, with crossover kings Sonic Boom Six taking on Flo Rida's smash hit, 'Whistle'.Enjoy it, and apologies in advance for putting that particular melody in your head! We've got another session from SB6 on the way this week (it's for their excellent new single!)http://www.facebook.com/sonicboomsix
