US Republican presidential hopeful Mitt Romney soon won't be able to use the music of Irish rockers Thin Lizzy to add excitement to his campaign stops.

According to the Independent, the wife of the late Phil Lynott has said there is no way the legendary Irish frontman would have supported the Republican candidate.

Caroline Lynott-Taraskevics, who is one of the controllers of the Irish rocker's estate, has instructed the band's record company to issue a cease and desist order preventing Romney from using Thin Lizzy classics in his campaign stops.

'It is too late to stop it happening, but it will prevent a recurrence,' she told the Independent. 'In America, the record company gives permission, so we have told them to issue a cease and desist order to the Republican Party.'

Both Lynott's wife and his mother Philomena were outraged to here Romney appear to the anthem The Boys Are Back In Town at the Republican convention in Florida.

Lynott's mother has said her son, who died in 1986, would have rejected any association with the Republican Party, particularly the Christian right-wing of the party and what she called its anti-gay and pro-rich policies.

In a statement published by premiere Irish music magazine Hot Press, Lynott-Taraskevics said that if Lynott were still alive he would back President Barack Obama and the Democratic Party.

'Absolutely in no way would Philip have supported Mitt Romney or Paul Ryan and he would have been so happy about Obama becoming US president,' she said.

Vice-presidential candidate Ryan made his entrance at the Republican National Convention to the famous Thin Lizzy classic.

Universal Music, which holds the rights to the Thin Lizzy catalogue, is reportedly issuing the cease and desist order to the political party. A growing line of rock stars have done likewise, including Silversun Pickups.
