Got a Light? (Mine's Burning Bright)

'James and Sirius are chosen to host the next speed-dating night, much to their chagrin, but things only get more interesting from there. In fact, James can't keep his mouth shut, Sirius is the chain-smoker who somehow smokes the least, Regulus has a bad case of RBS, and everyone but the speed-daters get a date (except Barty 'Babe Magnet' Crouch).'
