'Line Of Duty' star Adrian Dunbar has delighted fans with a rendition of an Elvis Presley classic at a music venue in London.

The 64-year-old Enniskillen man, who played Superintendent Ted Hastings in the hit police drama, sang 'That’s All Right' when he took to the stage at the QT jazz bar underneath the Middle Eight hotel in Covent Garden last Friday night.

Dunbar, dressed in a white shirt and dark blazer jacket, was accompanied by a live band and back-up singers as he sang the Blues track.

His impromptu performance appeared to go down well with the crowd, who can be heard cheering and clapping along in a video taken at the event.

That’s All Right was originally written by American Blues singer Arthur Crudup and recorded in 1946.

Presley later recorded his own version, which was released as his debut single in 1954.
