The labels are of an American copy. The UK number in the listing is MT 100, which would have been the very first from Pye after they took over UK distribution.
Only one title is the same, so Pye obviously decided to combine 2 US "A" sides. The other US side is from 70782.Check Crew Cuts' listed US 78s. Hopefully someone has MT 100, the very first Pye release from Mercury. [reported to Mods].
