Casual listeners can't be blamed for equating the Bee Gees with the dance floor bonanza they reaped through 1978's Saturday Night Fever, yet that commercial zenith was actually the culmination of a comeback for a group that had seemed washed up by the early '70s. One Night Only thankfully takes an even-handed view of both their original late '60s hits ("Massachusetts," "To Love Somebody," "Lonely Days"), building from a cannily Beatle-browed vocal sound, and the '70s blue-eyed soul ("Jive Talkin'," "Nights on Broadway") that led them naturally into disco. The Fever hits are here, as are Gibb originals that clicked for other acts; the family circle also widens for a posthumous duet with their late brother, Andy Gibb, while Celine Dion gets star billing in the collaborative "Immortality." --Sam Sutherland
