The film is based loosely on the life of the Irish Tenor, Josef Locke (1917-1999), played by Ned Beatty. The films exposition begins in Liverpools Irish community, with Micky ONeil (Adrian Dunbar) running Hartleys Night Club. Micky is a bit of a rogue, and although he considers Nancy Doyle (Tara Fitzgerald) his girl friend, he seems conflicted in saying "I love you". Following a disastrous love scene, where Nancy briefly shows us all, Micky attempts to win Nancy by booking a series of impostors, including Franc Cinatra (Joe Cuddy) and Mr X (William Hootkins), a Josef Locke impersonator -- who travels under the X since the real Josef Locke is wanted in England for tax evasion. When Micky finds that Nancys Mum Cathleen (Shirley Ann Field) was Josef Lockes special girl in the 1950s -- he tries to hook them up. Another disastrous love scene (no nudity), and Micky loses his job -- vowing to find the real Joe and bring him back to England from his exile in Ireland to perform for Cathleen and thereby to win back Nancy. The rest of the film covers Mickys search in the beautiful emerald isle, with a triumphant final performance of the real Joe at the about-to-be-torn-down Hartleys. The tunes are classic Locke, although sung by Vernon Midgley. (There is a CD of the same name with original Josef Lockes voice with recordings of 25 of Locke standards). The closing minutes of the film have the bulldog policeman Jim Abbott (David McCallum) closing in on Joe -- "Is it or isnt it?" the motto of Mr. X. belies the ending where the final scam plays out.
