Thank you. Here's the collection.
In this file, they're all in the key most commonly used in Moldavia, which suits an A whistle or fiddle. At Whitby I played the Bulgáros on a C whistle, which puts these tunes in the key most often used by folkies in Budapest. Take your pick.

The second is much more archaic with some seriously out-there whistle ornamentation - I might try that next year, but no way could most Eurosessioneers pick up the tune through all those twiddles and no melodeon could respond fast enough.
This shows the dance though it's musically off beam (played ok, but that lineup is western Transylvanian, not Moldavian):

BTW the name of the dance is misleading - it's called that by Hungarians in Romania but it's probably Serbian, not Bulgarian.
I may come back to "Pingvin". It has an amazingly complicated story.
