In 1990 on the album Oranges and Lemmings she sang `` The Trains of Waterloo '' , a funny version of the folk song `` The Plains of Waterloo '' in a duet with Martin Carthy . In 1994 on Gnus and Roses she sang `` The January June '' , which made fun of her sad and serious singing style . So far Tabor has performed on 3 of their albums , the 1990 Oranges and Lemmings ( singing `` The Trains of Waterloo '' , a parody of the folk song `` The Plains of Waterloo '' in a duet with Martin Carthy ) , the 1994 Gnus and Roses ( singing `` The January June '' , a send up of her perceived sombre character ) and the 2003 Yelp !
