I'm getting the Esperanto hymn-text "Glorkantas angheloj" ready to post in my hymnal, and note that the tune it's set to is named "Portadown" but bears little or no resemblance to the tune by that name in the DT, and more than a passing resemblance to what I think of as "Bendemeer's Stream". Anybody know what's up? Is this tune in British hymnals, say, under the name Portadown? Or was there a Portadown lyric (not the Prod one in the DT) that antedated Bendemeer's Stream? Or what?
