Time that someone remarks about the unnecessary and bizarre antics of *some* backup-vocals arrangements. To my ears, the chorus-y, syrup-y background choirs used in certain fifties & sixties titles render the specific productions unlistenable. Those arrangements should have been left to the dated "jingle" market that persisted on tv and radio ads for so long. For which they were well-suited; think "DoubleMint" or similar.
It was the vocal equivalent of adding strings to make a prestige recording effort sound more posh. And it's not the hip vocalese of, say, Lambert, Hendricks & Ross that is in question. It was the sound of mediocrity, and it wasn't limited to obvious occasions like Doris Day records. Dozens and dozens of otherwise superb recordings by everyone from Nat King Cole to Dean Martin to Louis Armstrong to Peggy Lee were 'sweetened' or 'smoothed out' for MOR-style easy listening--- funny even to hear those descriptors in 2013-- and made into instant losses, with no fault or misstep of the artist.
It may be an area where playlisted sound-files have the edge on Lps. Embedded in an unchangeable Lp sequence, even one or two of these luxe-chorus outings can deter the listener. Haven't heard this P.Cline Lp in too long to recall, but those drippy backups are worth avoiding when they occur. They may sound clever or ironic on 'MadMen' --but on record, they just sound like The Suburbs.
