Standing ovations usually come at the end of a performance, but for Russell Watson, the audience were on their feet from the moment he stepped on the stage.
A rousing rendition of the National Anthem set the scene for this Jubilee celebration and a night of music and patriotism to come.
Rule Britannia, Jerusalem and Land of Hope and Glory all featured, with many members of the audience waving flags.
Other crowd favourites included You Raise Me Up, Bridge Over Troubled Water and an emotional rendition of Bring Him Home from Les Miserables.
During We Are the Champions, Watson walked through the stalls to greet fans, sign autographs and pose for pictures.
The London Concert Orchestra was simply spectacular from start to finish. The musicians were led by a bare-footed Robert Emery whose charisma shone throughout the show.
Watson was joined by special guest, Laura Wright to perform Amazing Grace. The award-winning soprano later stunned the crowd with Stronger As One, the official Jubilee anthem.
The Jubilee celebrations may now be drawing to a close, but Russell Watson gave the Portsmouth Guildhall a right Royal knees-up and a highly entertaining evening to remember it by.
