I really should have brought the Dachshund choir. A serious oversight! Nothing adds spice to a song like a nice tight group of Dachshunds howling mournfully along on the choruses and scatting on the instrumental breaks. By "tight", I mean you give them each a little shot glass of schnapps just before the performance begins. That really brings out the Caruso in them. ;-) More than anything else, they LOVE harmonica music and will howl along with gusto.

Here's a nice video of a Dachshund singing along with harmonica. As you can see, he really likes it. Note the wagging tail.
