No, you can't.
You can use your Xbox360 Wireless headset to play!

guitar hero, yes, band hero, sometimes.
usually a dynamic microphone is used for live performances such as a rock band because its not as sensitive as a condenser mic which is used for recording.
you can use it for the bass, guitar, and drums, just not the microphone
Just about any Logitech USB Microphone will work! Even an Xbox360 Headset will work.
Don't use the Wii-mote on the instrument select screen as it automatically assumes you will be using a microphone. Instead use the buttons on the Guitar or Drums.
