Following up on 1997's Standing Stone, the concept behind Working Classical was to place pre-existing (and in some cases, very well known) McCartney songs into an orchestral context. Specially for this project, McCartney also unveiled some new pieces, namely "Haymakers", "Midwife", "Spiral" and "Tuesday". A different performance of "A Leaf" was originally released on 21 April 1995 on a CD single, and is presented here in a new recording.
Performing the new arrangements are the London Symphony Orchestra and the Loma Mar Quartet, with special orchestrations arranged by noted musicians Richard Rodney Bennett, Jonathan Tunick and Andy Stein.
