Adam: Here's a fairly straight-forward mash-up courtesy of the Who Boys. It mixes the marching guitars from the Clash anthem "London Calling" with the White Album lullaby "Cry Baby Cry." Credit goes to John Sakamoto's column in today's Toronto Star for finding this one. I'm not a huge fan of these sort of things as they're typically the marriage of a band I like with a band I dislike and that usually does little to redeem the latter. Fortunately in this case, both halves sit just fine with me.
