Apparently if you do a Goggle Search you'll come up with this song listed on an old Colombia record but no lyrics posted:

JR 30* SIDE 1: TIGER (Bring 'Em Back Alive) (Story adapted by Peter
Steele and Hecky Krasno from Frank Buck's "Bring 'Em Back Alive");
FRANK BUCK -- Merrill E. Joels, narrator, with supporting cast. Vocals
by the Southernaires. Orchestra conducted by Spencer Odom --
RHUMPY THE RHINO. Craig McDonnell as Rhumpy, Karl Weber,
narrator, with supporting cast and orchestra.

Hope that helps,
Charley Noble
