Thanks. It's a Kanilea 8 string, which I bought from mgm on ebay a couple of years ago. It sounds good for things like this. It's also louder than a normal uke. You can't play it for too long as it will kill your hands.
This site doesn't have tabs, but there are very clear videos of 'Wildwood Flower' played bluegrass and clawhammer style on the uke - along with some other tunes, as well: http://www.manythings.org/ukulele/
And here are a couple of nice tabs I've found online, as well:
I tried to look at this video but it's no longer available - I did eventually find some tabs though, courtesy of Ken Middleton's pages - thanks Ken, it's beautiful! Plenty there for poor old me to work at!
