Milhaud's Christophe Colomb was recorded on a London Decca (I think) LP
set conducted by Boulez (I don't know the year) TW 91084--TW 91085.  I can
try to get more information.  I seem to recall a Fanfare review of a CD
recording of more recent vintage 4 or more years ago but am not sure.

As to Delius' Magic Fountain, Norman Del Mar conducted a recording that
came out on Arabesque (8121-2L Arabesque) around 1980.  (LP I think.)
