You're right about that cross, Rick.
Even now, people will denigrate the Corries for being popular. I went to see the Corries in concert many times. They could get a whole audience singing, two and three-part harmonies. (Even in Edinburgh)
Long before "Celtic Music" became hip or trendy, they would sell out concert venues for a week at a time.
Roy Williamson's song "The Hills of Ardmorn" is one of the most haunting, evocative pieces of music I have ever heard.
Ronnie Browne is still with us, still working, but Roy is sadly missed.
