According to Record Collector (No 91): " Costello had been signed to Radar in 1978, via a licensing deal from Riviera Global Productions. Radar collapsed towards the end of 1979, and so Elvis's manager Jake Riviera alighted upon the Specials' 2-Tone label as an ideal venue for a holding operation - a one-off single - until Elvis sorted out a deal for the Get Happy!! album. WEA, who had distributed Radar, were less than delighted: they felt they had a stake in Costello's career by virtue of the success of the records they had distributed for him, and so they obtained a court injunction to stop the 2-Tone single being sold.
By March '80, the situation was clarified: F-Beat was set up by Riviera as an independent company, but WEA continued to distribute their records. In the meantime, there were several thousand 2-Tone singles to dispose of. These were handed out free to the audience at a London's Rainbow Theatre gig. Several months later, Riviera pressed up a few thousand more of the 2-Tone singles, and these were given away at London and US gigs".
