I have no problem singing along when its cranked up, drive around with Time by Pink Floyd cranked up and you'll catch yourself singing along too.
Sing to my gf to make her laugh, sing to McFlyday on Radio1 on the way to work. most of the time find myself singing in front of the monitor like the yuma yuma bloke, just have the sense not to record it. Plus, im probbly 8 stone lighter.
Sometimes when drunk, often when I'm in uniform. Something about being in uniform and any form of transport results in mass singing.
