Born in 1936, Silvo started his career playing skiffle and jazz and singing solo in nightclubs.
In March 1967 he appeared with his own Johnny Silvo Folk Group on the Alex Campbell and His Friends LP alongside Sandy Denny.
A month later an LP called Sandy and Johnny was released in which the two singers alternated songs.
Silvo also performed for nine years as part of a duo with Dave Moses.
Silvo died on 19 December 2011 aged 75, a few weeks after his birthday.
