A couple of the guys from Glasvegas were friendly with people that lived in the flat above me a couple of years ago... never spoke to them but heard instruments being played in that flat all the time so I don't know if they were collaborating with the guys upstairs or if they just messed around or what the deal was. Pretty cool though (and nothing to do with this thread really
)
Dykeenies are another Scottish band with quite a strong accent. I love their song Stitches, it's one of my favourites.
