UPDATE!!!!
Yes, It's a McCann Duet - It has 80-something keys and it is BIG!
However I know the actual tunes I'm going to play inside out - I just don't know them on this instrument. And my co-ordination is getting there (my party trick is doing a "Charles Ives" for those who know what I'm talking about)
3 Days in and I've just realised how amazing instruments concertinas are - they rock!
BUT....to all those who doubt my willpower to succeed I will announce the date and time of my debut performance when I found out myself - I'll also quite posibly upload a sound or video clip to somewhere so I have documentary evidence.
Oh, yeah and I am a member - I'm just still at my parents house and havn't logged in properly.
