Laurie berkner has CDs out, I am sure you could possibly find them at your local library. I'm not sure who sings the other songs though, did you look on the noggin website. They might have songs or artists listed on there and where they are available. in fact amazon has the season 1 soundtrack to jacks big music show but I don't think the songs you are looking for is on season one. My daughter loved that show when it first came on but doesn't watch it much anymore so I only know the family song. We loved to "Dance Party Yipee" LOL.
Hope this helps :)
