the song of yodeling!=)

from the soundtrack listing:
"Yodle-Adle-Eedle-Idle-Oo"
Slim Performed by RANDY QUAID
Yodeling by RANDY ERWIN, KERRY CHRISTENSON
Willie Brothers Performed by DAVID BURNHAM, JASON GRAAE, GREGORY JBARA

well, he did, kinda... but they provided him with 2 (!!) stunt yodlers!! *ggg* so, sum up: he did sing. but if you pay attention, the parts that aren't yodelling aren't extremely challenging either... ;)
