Micky O'Neill, a sleazy Irish entertainment promoter has about run his course offering pseudo-acts like Franc Cinatra. The Ryan family that owns the theater is about ready to throw him out when they ask who his next performer is "Bing Crosby spelled with a K"?, but Micky O'Neill comes up with the name of Josef Locke and the Ryan's gasp as Josef Locke is supposedly out of the country, because of tax fraud or something. So Micky is given a reprieve until it becomes known that the Josef Locke he has booked is a fraud, Since his girlfriend's mother once had a fling with Jo and has been duped by the fake Jo, Micky has been outcast by the Ryan family, his girlfriend and especially his girlfriend's mother. He hops a ride on a boat to Ireland where he meets up with his friend Fintan, a concert promoter, and the two of them ride through the Irish countryside in search of the real Josef Locke in an effort to convince him to return to England to perform. When they find him, the Irish comedy really begins, and also the Irish singing. The tenor voice is spectacular and when Jo sings, women weep.......
