This is the soundtrack to the excellent film of the same name, and is pretty much the same thing as the film - a big homage to Cole Porter by today's artists. Essentially a tribute album, but with some rather unexpected stars appearing. Robbie Williams (no stranger to this style of song) clearly loves every moment of singing the title track, and does do it justice. However, the appearance of Alanis Morisette and Mick Hucknall took me more by surprise, but still their performances are superb. Morisette particuarly benefits from showing a sweeter, more quiet side of herself. Elvis Costello's performance is visually hilarious (consummate showman that he is) so it's worth seeeing the film as well.
However, it's also a good collection of songs, because it tries to encompass the very best of Porter's songs in one album (which you'd never get in one show, for instance).
I think the quality of the lyrics really sells this album though, cos Porter's song-writing is timeless - clever and sweet, and delightfully funny. This is the only man in the world who could have written a seduction song and got away with a line about educated fleas...
