IMO Emotion really comes out when you're playing or singing your own material. When I recorded Farewell to Kintail ( The first tune I composed after getting into band in a box 7 years ago ) I had tears in my eyes. I was picturing the area as I was playing it and thoughts of holidays in my childhood were coming back. It's also the area we were in when myself & my wife did our first gig together. It's the same area where I played my first gig in public as a 17 yr old.
The only one that came close was a song I wrote years before I stopped playing. It's on you tube called The Highlands is the place for me. The singer is the Late Sylvia Marie Barber from California. A dear friend and one of the finest accordionists in the USA. Sylvia fell in love with the song after I sent her a copy from an old tape I'd recorded. She asked if she could record it with me. We had a load of laughs getting it done as she kspt getting her pronounciations wrong. Lots of good natured ribbing took place before she finished it. Sadly she died before she could hear the finished version, so I got a professional musician friend of mine to help out with the backing, along with our own Keith Scott on piano. The end result was brilliant and I must confess to having an eyes full of tears when I was recording my part.
