If you nestle the microphone in a wrapping paper tube, prop it in the crack between the cushions of the couch, align the drums in front of the crack, sit atop six or seven decorative pillows piled on the crack, and straddle the wrapping paper tube, you can play the drummer and the singer at the same time quite nicely on Rock Band.

By the way, in case you're in need of a name and want to copy, our sibling Rock Band name is Massacre On Heaven's Grave.
