For the interest of those within reach of Ontario, there are Simon Mayor and Hilary James duo concerts in Orillia on 27 April, and in Goderich on 29 April, 2001.
The notice I rec'd did not include locations, sorry.
Simon is one of the few masters of the mandolin and one amazing guitarist. Hilary is a wonderful interpreter of trad songs and a writer herself. She also plays bass and guitar. Together they are witty and talented in the extreme. They have several recordings (trad, blues, original, and classical) which can be found at www.AcousticRecords.co.uk
Simon has been probably my biggest musical influence in the last ten years and I can't recommend this enough. Some of you may have seen them at the Goderich Celtic Festival in the past.
