by Stephen CookJust one in a long line of Mancini's excellent '60s soundtracks. This time out he's back scoring another of Blake Edwards' comedies, The Party. Featuring a Hollywood producer's cocktail party and one hapless Indian actor (Peter Sellers) who is mistakenly invited, the movie called for plenty of lounge slickness and some romping interludes. Enter Henry Mancini and his usual bag of almost-transcendent vibe and strings jazz and mod swingers. And tagging along are such Mancini veterans and class players as tenor saxophonist Plas Johnson, pianist Jimmy Rowles, and drummer Shelly Manne. Pity, then, that instead of the lovely Claudine Longet vocal turn on "Nothing to Lose," listeners only get the fine yet disappointing instrumental version. A minor quibble, really, in light of all the high-end booty to be had.
