There have been a ton of "learn Spanish through kids music" disks that have come across my desk over the past year or so, but few of the songs have been as effective in teaching a few Spanish words (or as fun) as Dan Zanes' version of the nursery rhyme "Pollito Chicken." It features Caridad De La Luz aka La Bruja as the maestra, and whereas before you could only download the video, now it's available for viewing on YouTube. BTW, the Spanish for "tie" (you'll see a lot of them) is "corbata."
