Then get yourself over to Amazon.com's Music Easter Store page, where you can find a stream of Catch That Train!, Dan Zanes' new album, scheduled to be released May 16, 2006. (Windows Media Player required to play, though samples are available for all the tracks in other formats.)
Having listened to the stream, I can say that anybody who's liked Dan Zanes' prior 4 children's music albums will like this one. It's just as good and with further listening may prove to be his best. Early favorite tracks include "Let's Shake," "Loch Lomond" (with Natalie Merchant), and "I Don't Want Your Millions Mister." (Considering Zanes' affiliation with Starbucks and Disney and fears that he'd "sell out," there may be other reasons for selecting that last track.) I would've ordered the CD sound unheard, but I pre-ordered it today.
Anyway, go now.
