Hockey Night in Canada stars Ron MacLean and Don Cherry made a surprise guest appearance Wednesday in a performance of A Funny Thing Happened on the Way to the Forum in Stratford, Ont.

MacLean and Cherry, as part of a walk-on scene with comedian-actor Sean Cullen, pretended to be lost and looking for the Montreal Forum, to the amusement and surprise of the audience.

"It was just incredible to see the response. It was overwhelming," said Stratford Mayor Dan Mathieson.

Cherry, dressed in a trademark loud jacket, and MacLean in a suit, bantered with Cullen on the Avon Theatre's stage. Cherry had dressed up earlier in the day as King Lear.

While on stage, Cherry quoted the opening lines of King Lear, including, "My story will be told by an idiot."

"Ron had a huge grin on his face when he said that," Mathieson said.

The pair were in town to shoot some scenes for Tim Hortons Hockey Day in Canada and to take part in the announcement of Stratford's plans for the annual celebration of hockey between Jan. 26 and 30.

Events include a Randy Bachman concert, hockey clinics and a photo opportunity with the Stanley Cup.

MacLean and Cherry took part in a press conference later in the day with Mathieson, who announced Stratford's plans for the week. Former NHLer and co-chair of Stratford's local organizing committee, Tim Taylor, was also there.

"Hockey Day in Canada is an important aspect in the dreams of kids that play hockey, and hosting it in our community allows us to take that dream and make it real for so many kids," he said.

Tim Hortons Hockey Day in Canada airs on CBC on Jan. 30, 2010.
