Sounds like you need pieces in the key of A major (F# c# and g# all use the third finger of the right hand). Some examples I've played from the ECD repertoire include: Long Odds, Lord How's Jig, The Bishop, The Dressed Ship, Elverton Grove, The First of April, Gathering Peascods, Geud Man of Ballangigh, Grimstock, Prince William, The Rakes of Rochester, Sun Assembly. I remember one gig where nearly the whole dance list was in A. There is variety in this list from the fairly straightforward to the finger twisters.
You're right - tunes in A major are good (and any other tunes with 3 sharps or more). Thanks for this list. I have never heard of them - where can I get the sheet music?
