Donald Trump appeared to ignore the demands of British rocker Paul Rodgers by using his hit All Right Now to cap off his presidential nomination speech.
Rodgers earlier joined a string of British artists including Queen, Adele and representatives of George Harrison to object to the Republican and his campaign using their material.
The billionaire tycoon accepted his party’s nomination at the Republican Party convention in Cleveland, Ohio, on Thursday.
Mr Trump ended the fiery speech with his campaign slogan “Let’s make America great again” and “I love you” before All Right Now’s famous guitar riff kicked in.
Rodgers, who wrote the tune in 1970 while a member of Free, previously warned he had alerted his lawyer to the song’s unauthorised use during the Republican convention in Cleveland, Ohio.
The song was used to introduce Mr Trump’s running mate, Indiana Governor Mike Pence.
Rodgers made it clear that using the track, written with Free member Andy Fraser, was unauthorised in a tweet posted on Monday which said: “Permission to use ‘All Right Now’ was never sought for or granted by me. My lawyer is dealing with this matter – Paul.”
Earlier in the convention Mr Trump walked on stage to the sound of Queen’s 1977 classic We Are The Champions, but the entrance was followed by a message on the band’s Twitter: “An unauthorised use at the Republican Convention against our wishes.”
Representatives of Beatles guitarist George Harrison said the unauthorised use of Here Comes The Sun to introduce Mr Trump’s daughter, Ivanka, was “offensive & against the wishes of the George Harrison estate”.
Adele’s hits Rolling In The Deep and Skyfall were played at Trump’s political rallies earlier this year, prompting her spokesman to point out she had not given permission for her music to be used for any political campaigning.
