A Mandurah line transit guard matched the high spirits of Shania Twain fans on Friday night by joining in on the post-show frivolities.
Mandurah woman Lisa Kelly said strangers danced together after the concert when she played songs on a speaker.
Ms Kelly said the mystery transit guard was a highlight of the train ride from Perth to Mandurah.
“He was really nice and joined in – all of the guards were fantastic,” she said.
“I am sure they are usually dealing with aggressive people so it’s a breath of fresh air for him to be able to have a bit of fun with train-goers.
“I usually do this after concerts for a bit of fun. Sometimes they let me do it and this was one of those occasions.
“If the guards tell me to turn it off I will, I am a law abiding citizen.
“We all had a great time.”
