The most memorable term I've heard used to refer to the boghran is "the Irish Chapatti".
"Hran" that's a new one to me. Sounds a bit Star trekky to me, the Hran would be the kind of guys who'd get on the nerves of your average long-suffering Klingon.
Prab to God tis fella doesn't turn up with bongo drums, or you'll be wishing he'd brought the bodhran. Mind, with two bodhrans, maybe he's planning to develop some nightmareish bongo-bodhran...
