Transcription Mystery Disc #73

I bought this Disc at a flea market. There was a filing cabinet and each drawer was full of discs. I bought half a dozen, and this one because it was odd. This is a particularly strange transcription because it is so well labeled, but none of it led to anything. What is The Abbott Champion?

That big label you see above was stuck on right over an Audio Disc label. There's a blank Audiodisc label on the b-side. The b-side is blank. As the label suggests it was recorded from the outside edge and spins at 33.3 rpms. This dates it to the 1950s which is congruous with the date on the disc of July 1958. There are two takes of the song on side A, I include them both. the second one has a sax intro instead of piano. Vocals are by District 12, wherever or whoever that may be. It's not a high school, these are clearly adult male voices. Perhaps a union? One hint is the label itself. Clearly many copies were made. I'd guess enough for the choir members, maybe extended family, maybe more but nothing retailable.
The lyricist and conductor is Ralph Spence. the song "The Happy Wanderer" was a popular song written by Friedrich-Wilhelm Möller after World War II. In 1953, BBC Radio aired the Obernkirchen Children's Choir performing the tune. It made the UK singles chart in 1954. In reading the original lyrics it's clear that this recorded version has slightly different words but I cant make them all out. So I know when, but not who or why or where.
