He’s all for making America great again, but Donald Trump has faced accusations of forgetting the words to the classic patriotic song as the United States Army Chorus sang it behind him.

The rendition of the Irving Berlin folk song was performed at an event organised at the White House.

He starts out confidently enough, but things rapidly disintegrate after the first two lines.

His mouth abruptly shuts over the line “Stand beside her and guide her”, and then kind of … flaps open and shut, completely out-of-step with the choir singing (and annunciating) behind him.

The event had been changed at the last minute after Mr Trump disinvited Super Bowl winners the Philadelphia Eagles based on the ongoing controversy of kneeling during the national anthem.

Suddenly Malcolm Turnbull’s Commonwealth Games stint isn’t looking so bad.
