She spent most of her time between there, Cape Breton and Boston. She played with Angus Chisolm, Alec Gillis and Alcid Aucoin who were part of the original Inverness Serenaders.
Betty was the featured pianist on all the Serenaders 78's, but in fact one of them had someone else - a piper - taking over piano for her despite her credit. I am told that she did have some trouble with performance anxiety in those days before Inderol, tho she did occasionally make medicinal use of whisky to control it.
She also performed with the IS and others on Boston radio station WHDH.
Betty had classical training - "8 years with the crabby old nuns" according to someone who knew her - and was exposed to jazz influences as well. These may or may not explain the hints of syncopation and the addition of VI chords on the recording of The Marchioness of Tu Lybardine.
The only easy way to hear any of her work at the moment is a fragment on the Tracey Dares video "A Chording to the Tunes". However, there are rumors of a CD rerelease of the Serenaders 78's late in 1999. If that happens, it will be noted at this web site.
Betty died in her fifties in 1964.
