The use of the Thin Lizzy classic 'The Boys Are Back In Town' at last week's Republican national convention in the US has outraged the mother of the band's lead singer, the late Phil Lynott.
Philomena Lynott has strongly objected to the use of the song which provided backing for the arrival on stage of Vice Presidential candidate Paul Ryan.
The song from the band's 1976 album 'Jailbreak', written by Phil Lynott, was a major hit for the band.
However, his 81-year-old mother says she is opposed to the use of her son's music, by the Republican Party because of its policies on gay marriage.
"I am really upset at Philip's music being used in Mitt Romney's campaign in a political way that Philip would not have approved of," she said.
"As far as I am concerned, Mitt Romney's opposition to gay marriage and to civil unions for gays makes him anti gay -- which is not something Philip would have supported.
"He had some wonderful gay friends, as indeed I do, and they deserve equal treatment in every respect whether in Ireland or the United States.''
She also stressed that her son would not have supported policies "of taxing the poor and offering tax cuts to the rich'', as proposed by Paul Ryan.
"There is no way I would want the Lynott name to be associated with any of these ideas,'' she said to 'Hot Press' magazine.
Lynott rose to fame in the 1960s and 70s as the unmistakeable frontman of rock band Thin Lizzy.
Lynott died of heart failure and pneumonia on January 4, 1986 aged 36.
In 2005, a life-size bronze statue of Lynott was unveiled on Harry Street, off Grafton Street in Dublin.
