Thanks a million, kat, and Mick for going over there and listening to them.
I've played 'Black is the Colour' that way since Barry Moore (aka Luka Bloom) released it on an album from 1978 called 'The Treaty Stone', so it's not quite my own arrangement.
The Wild Rover ended up that way after years of requests to play it 'RIGHT' On the Bothy Band's 'In Concert' album, Paddy Keenan starts off 'The Bucks of Oranmore' (key of 'D' ;-)) at regular speed, until 'The Demon Clappers' start accompanying him at varying tempos. Paddy slows the whole reel down, until the 'Clappers' get the message.
The Wild Rover is a very beautiful song, but the sentiment can (does) get lost in the delivery. I play it through DAGDAD in the key of 'F'
All the songs, barring Black is the Colour', and 'I don't want to know' are in DAGDAD. The former being in Standard tuning, the latter in DAFDAD.
Two of my guitars are in operation, there; my Limited 'Washburn D92', which stays in DAGDAD, and an old Tak that I've had for years. I normally carry 3-4 guitars around to gigs; the Wash, the Tak, a Cort Silk & Steel, and my Morris 9 String. I'll be sticking a few pictures up on the site of the guitars, shortly.

I'm off to Copenhagen later this morning for the preparations for The Copenhagen Irish Festival which starts on Thursday, so excuse the brevity of this post.
I'll check in during the week, but in the meantime, thanks a mill, again, katmeluv and Mick, for the kind words.

Talk to you again, soon.
All the best.
