The National Mall Has The World's Largest Kiddie Pool...

... so why wouldn't you host a kids' music concert there?

OK, that probably wasn't the thinking of XMKids when they set up a concert for Saturday, May 24, but, hey, why not? The XMKids' Traveling Roadshow will broadcast from 11 Children's Miracle Network hospitals across the country starting May 12 as part of an effort to raise $10 million for the non-profit group.

And at the end of the trip they'll host a live, free show from noon to 4 PM at the Sylvan Theatre on the National Mall. Musicians playing at the show include Lisa Loeb, Meredith Brooks, and the ubiquitous Jimmies, who are well on their way to becoming the Jack Johnson of this year's summer concert circuit, appearing seemingly everywhere.

Nice lineup for a good cause.
