BMG has released an extraordinary four-disc set of Sir Noël's complete HMV 78RPM recordings, and therefore to list them here would be pointless.  

Several single disc collections are also available, however, such as:

Noël Coward And Gertrude Lawrence

Pearl Flapper (PAST CD 9715 UK) 1990

The Compact Coward

EMI (CDP 7 922802)

His later recording are a bit more difficult to come by, however, and it is these we will concentrate on.

Conversation Piece (1951) Columbia, 2LPs, app 90 minutes.

An extrarodinarily charming version of one of Sir Noël's most enjoyable shows, this recording features, along with Sir Noël, the talented Lily Pons and a young Richard Burton.  Sadly, we have yet to see in on CD.

Live At The Sands, Las Vegas (1955)

Medley, Uncle Harry, Loch Lomond, A Bar On The Piccolo Marina, World Weary, Nina, Mad Dogs And Englishmen, Matelot, Alice Is At It Again, A Room With A View, Let's Do It, The Party's Over Now

Noël Coward In New York (1956)

I Like America, Louisa, Half-Caste Woman, I Went To A Marvelous Party, Time And Again, Why Must The Show Go On?, New York Medley, What's Going To Happen To The Tots?, Sail Away, Wait A Bit Joe, 20th Century Blues, I Wonder What Happened To Him (The Indian Army Officer), The Party's Over Now

note: these two albums were re-issued (1969) as a double album by Columbia, under the title The Noël Coward Album.  It was then issued (1991) on compact disc minus the following tracks:

The Party's Over Now (live), New York Medley, I Wonder What Happened To Him

London Morning (1959)

An amusing and enjoyable ballet score, conducted by Geoffrey Corbet with the London Philharmonic.  Re-released in 1978 by DRG as part of the LP A Special Event (SL 5180), along with the EP Noël Coward Sings Hit Songs From High Spirits (see below), and the two songs Sir Noël and Joe Layton recorded for a special single to be given to the Broadway cast of Sail Away.

High Spirits DRG 13107

Sir Noël didn't write the music, but he directed, and this CD release of the London cast recording features Coward's EP Noël Coward Sings High Spirits- Hit Songs From The New Musical Play, recorded 4 September 1964.

Something Tells Me, If I Gave You, Forever And A Day, Home Sweet Heaven

Bitter Sweet (1989) ENO?, 2 CDs, app 84 minutes

No Noël, simply a magnificent recording of his entire score by the English National Opera, featuring the lovely Valerie Masterson.  Get it.

The Grand Tour (1995) Silva Classics (SILKD 6007) app 60 minutes

Robin Wright leads The City Of Prague Philharmonic in a stereo recording of London Morning, as well as Hershy Kay's ballet adaptation of some of Sir Noël's better known songs, The Grand Tour

An album of songs from the show Sail Away was recorded and released, but unfortunately I have no information on this.

Recordings Not Originally Intended For Release

Together With Music DRG (DARC-2-1103) app 76 minutes

With Mary Martin, originally broadcast 22 October 1955.  

Originally released on DRG as a 2 LP set, this features the audio portion of the entire TV Special.  The CD release only features about 50 minutes' worth.  This is unfortunate, as the entire 2 LP set would have fit comfortably onto one CD.  Nonetheless, either version is well worth searching out.
