Gary Shearston interviewed by folklorist Jim Low Mark Gregory referred to this interview in his post above.

Several years ago he popped into a small festival I was attending (he was in the same town) & sang us a few songs. It was the highlight of the gathering.

Gary Shearston, Australian singer and songwriter, was a leading figure of the folk music revival of the 1960s, especially remembered for his authentic versions of old 'bush' songs (folk songs). Gary achieved international success as a songwriter (e.g. Sometime Lovin' performed by Peter, Paul and Mary) and as a recording artist (his distinctive version of Cole Porter's I Get A Kick Out Of You was a hit in 1974).

Over the years his music has absorbed and adapted a diverse range of elements including Australian aboriginal and West Indian reggae (before either was popular with mainstream western audiences). In 1990 Gary Shearston was recognised in Australian country music with the Tamworth Songwriters' Association's award for Bush Ballad of the Year.

Over his active recording life of some 50 years he wrote, sang and recorded wonderfully evocative and distinctively Australian original songs. Much of Gary's songwriting has reflected a 'spiritual' thread and many more recent songs reflect on his interesting life as part of the arts, folk, and social activist movements since the 1960s. Gary's songs from 1964 to 2013 are available on CD and reissued 'archive CD' (CD-R).
