Ideas for a playstation 2 wireless microphone

hi, I was recently given a wireless microphone for a ps2 game called dance UK. The person I got it from didn't want it and I thought it might be useful(I'm a junk collector ;D) it plugs into the controller port and the scart adapter, it seems to draw 12v from the ps2 for the transmitter, has an input cable for the microphone and an output cable to the scart adapter. On the scart adapter there is also a jack for an external speaker. Finally after some thinking about what it needs the controller port for; I decided it might be for volume control (it also says volume control on the bottom :P) Does anybody have any ideas as to what I could use this for? (I don't mind rigging it as long as it's not TOO much)
