Here is a link to the new Dutton release of Vaughan Williams unrecorded works:

In addition to the early Serenade in A minor for Orchestra and David Matthew's realisation of fragments from the incomplete Cello Concerto, the CD includes the Bucolic Suite and an orchestral suite, arranged by Roy Douglas, of Folk Songs of the Four Seasons - the choral and orchestral version which was previously recorded by Albion.
This looks a most interesting CD for those who love Vaughan William's music.
