Back when I recorded the twins, more than 2 years ago when they were just in kindergarten, I tried uploading some of the files to Ourmedia, which is free. Well, it didn't work very well, so I never went back. But three of them did make it up and I want to make sure they're preserved for posterity:
Take me out to the ball game - Wil
O Leaphart - Wil
If you have time, give them a listen. They are so sweet!
