While waiting for the bus in London, YouTube user FakieLeatherman came upon a tuba player being asked (harrassed?) to "just blow the bastard" by a passer-by. So, the busker complied ... in style!

Meet Christopher Werkowicz AKA Fire Tuba guy, as interviewed by Emma Spedding of Streets Got Talent:

With a fire horn I always come across a council officer or police that say it’s dangerous. It helps me explain that I do special effects for film and theatre for many years that the elements of which I built this devilish invention are certified and come from stores. They all say that the next time I’ll meet you here-prison. But a little adrenaline in the life of a Busker is good!
