Denver's solo recording contract resulted in part from the recording by Peter, Paul, and Mary of his song "Leaving on a Jet Plane", which became the sole number-1 hit single for the group. Denver recorded songs by Tom Paxton, Eric Andersen, John Prine, David Mallett, and many others in the folk scene. His record company, Windstar, is still an active record label today. Country singer John Berry considers Denver the greatest influence on his own music and has recorded Denver's hit "Annie's Song" with the original arrangement.
