'Reckless Jane' was penned by Drake and Martyn just months before Drake died. The two wrote the lyrics together and first began working on the music during a jam session in Martyn’s home in Hastings.
The track is an aching and timeless folk lament that only serves as a reminder of how Drake was taken from the world far too young.
Speaking to The Independent, where the track is premiering, Martyn said: "I couldn’t even think about the song for so long because it brought up so much pain. It took a while to finish after that point.
"The song came out of a bit of fun. We tried to think of all the things we could rhyme with Jane, but ‘hear her laughing like a drain’ didn’t make the cut!"

The 'Jane' in question is said to be partly based on Martyn and other female ‘muses’ - two of which were called Jane.
Beverly Martyn’s new album, The Phoenix and the Turtle, is released on 22 April.
