In the early 1990s, Robin Holloway transcribed Haydn's string quartet, op. 42, for piano duet.  This was one of the many quartets not included in the 19th century Peters Edition transcriptions of selected Haydn Quartets. 

This initative was to be the first step in a long term project: to fill the remaining gaps in the cycle of transcriptions begun by Peters. 

The transcriptions were completed in 2008 in time for Haydn's bicentenary celebrations.
