If you send me your address I will send a free Cd tutor on a twenty button Anglo.Mainly English style however it does not cover Irish playing.There are also some free MP3 downloads on my site and the music which accompanies the tutor.
There are no DVDs or vidios to my knowlege,but John Kirkpatrick was working on one.
Owing to the various layouts for keys above twenty there is a major difficulty to cater for this market.I am not sure that it can be done, but good luck to someone having a go at it.
