Hey Toadfrog,Boring music is more a product of the performer than the tunes used!
My band Tursacan's Gaelic songs are done in a contemporary manner, use didgeridoo (we are from Australia) and we make connections (song wise) between Australia and Scotland, Man, Wales, Brittany, Galicia, and Ireland.
Our songs "aint" boring, indeed, rhythmically and melodically, many gaelic tunes, "celtic" tunes are very stimulating.
Its all in the arrangement and in the PR.
And I really think that using Scots accents as a joke is quite an insult.
