Described on the cover of OUP’s volume of classic arrangements, In The Mood, as ‘an opulent showstopper’, Over The Rainbow is a rich and slushy arrangement for SATB with lots of Divisions. It has become one of the most often performed of this book of classic arrangements.
It has been recorded by the Oxford Pro Musica Singers under Michael Smedley (on PROUCD141).
In The Mood is available from music shops or direct from Oxford University Press
There is also a version available for AATTBB.
