Christmas Single is the second Christmas single by the American punk rock/punk pop band Mx Px, released in 1999 (see 1999 in music). This single was sent out to all members of the http://pxpx.mxpx.com MxPx Fanclub at the time, and being a member was the only way to get one. They have continued the tradition of making a Christmas single every year and sending it out to their fan club members.
