Howdy Mudcat friends!
This is Matt from Sing Out! Magazine. I can confirm that p 28 of Vol. 33#1 contains the music for "Hi-Ho-Jerum" and p 128 contains a letter about the song from Barney Baley. We don't have backissues of 33#1 & 33#3 in-stock, but we can send PDF copies for a small $3 USD donation.
See our website [www.singout.org] for contact info!
Keep on Singin',
