Have heard a version of Waltzing Mathilda recently sung very slowly and hauntingly by a very deep, gravelly voiced male (black?) singer. Have had no luck locating. Any ideas who this might be??

The singer is Noel Watson (certainly not black) his version was picked up by a television chanel and used on a bicentennial program back in 1988 , and made number 16 on the pop charts.
Noel had been performing since childhood in many bands including , The Thunderbirds , Tamlas and Saltbush ...... He performed his version of Matilda at many venues including the AFL grand final and countless TV shows.
Today Noel lives a quiet life in Central Vic after some health issues and rarely performs.
