I've two copies of English Columbia 3546 R. One side is The Faery Song from Boughton's "Immortal Hour," matrix A 3551-5. The reverse is Easthope Martin's song, "The Minstrel," matrix A 3817-1. The singer is Philip Heseltine.
The "R" indicates "remake," as far as I can tell, and replaces an earlier, idenical coupling.
One copy has the take number after the matrix number in the dead wax, the other the matrix number only.
What's going on here? Is one a dub? Any idea?
