My friend, Mylo Hatzenbuhler, has some music, musical comedy, and comedy on-line. You can check out his "A Loan Again" and "Born at the PCA," (not a denominational reference), as well as a snippet from one of his convention appearances (link). He has an official YouTube page, where you can listen to his hit, "Heifer Bells."
You can also hear him weekly on 1450 KBMW or catch the podcast (here's the intro segment), and the first Friday of the month on KFYR-AM. He's also on the air on Wednesdays on KOVC 1490-AM (www.newsdakota.com) at about 6:40 a.m. Central Time.
Of course, you should check out his website: Farm Boy Music, including the store, where you can pick up his CDs.
His good buddy Clyde Bauman is also quite the singer and is featured in some of the non-comedy selections at Farm Boy Music.
