Stewart has described the song as "one of the greatest love songs ever written.

“The guy goes to his death 15 minutes the next morning after he’s been married."

The BBC refused to allow Stewart to perform the song last year "because of its Irish, anti-English overtones in the song,” claims Stewart.

In 2016, Glaswegian band Glasnevin attempted to get their cover of "Grace" to top the Christmas music charts.

The beloved ballad was written by Frank and Seán O'Meara in 1985 and has been recorded by many musicians, most notably by the late Jim McCann, who ensured its lasting popularity as a powerful rebel song.
