A video has surfaced online showing Rod Stewart belting out Grace alongside Celtic chairman Ian Bankier and chief executive Peter Lawwell.
The clip, which is understood to have been recorded in Rome last week, shows the legendary crooner belting out the Irish folk ballad as he urges his fellow dinner guests to get involved, reports The Daily Record.
Bankier, who is sitting on the left hand side of the 74-year-old, rises to his feet and joins in with Sir Rod as he chants the hit made famous by Jim McCann.
The camera pans around the room and Lawwell is visible as he also shows off his singing voice.
Stewart's close pal and Celtic songwriter Jon McLaughlin is also in attendance as the Hoops hierarchy enjoyed a night to remember.
And the trip to the Eternal City will live long in the memory for Celtic supporters as they watched their side secure a place in the last 32 of the competition with two games to spare.
Olivier Ntcham 's brilliant last-gasp winner against Lazio sent the Hoops supporters inside the Stadio Olimpico into raptures.
