U.K. was a very cool band if you like progressive rock, it featured John Wetton and Bill Bruford of King Crimson, Allan Holdsworth on guitar and Rick Wakeman on organ,keyboards and former Curved Air violinist Eddie Jobson.
IMO their best album was the self titled album which contained their most famous song 'In The Dead of the Night', their second and last album is not bad but it is missing Allan Holdsworth guitar work, and the band is down to trio. This is one of the few albums I own where their are no guitars played on it. Well Wetton does play bass guitar.
