Stanley Kirkby, whom was part of the Minster and Meister singers, also worked under other names, Walter Miller, James Baker, J. Kaye and probably others.

Wilfred Virgo made cylinders with Walter Hyde and Peter Dawson.

Ernest Pike recorded under some 10 names and with many partners; he sang and recorded in Gilbert & Sullivan operettas and did many of the favorites of the 1900-1910 period.

These three, along with Peter Dawson, made recordings of Kipling songs and some sea songs, but I think I have all of their chanteys in the short list above.
