Song of the Day 2/1: Catherine O’Hara and Eugene Levy (as Mitch & Mickey), “A Kiss at the End of the Rainbow”

Catherine O’Hara, who died unexpectedly Friday, was rightly praised for her comedic chops, but she could also sing a little. Her sister, Mary Margaret O’Hara, is a well-known vocalist in their native Canada, so it runs in the family.

Catherine and Eugene Levy played opposite each other for more than 50 years, starting on SCTV and running through “Schitt’s Creek,” and had such great chemistry that many people thought they were married in real life. They were never more poignant together than in Christopher Guest’s satire of folk music, “A Mighty Wind,” where they played Mitch & Mickey, a duo whose marriage and partnership fractured years before and were now reunited for a charity concert.

Most of the film’s songs were spoofs of folk tropes, but its emotional climax was a romantic ballad that the couple had traditionally sealed with a kiss. After all those years apart, would they or wouldn’t they?

O’Hara learned to play the autoharp for the part, which she and Levy reprised when the tune was nominated for an Oscar for best original song. It was written by Michael McKean, who played one of the Folksmen in the movie, and his real-life wife, Annette O’Toole.

“When You’re Next to Me,” was shot for the film but only played over the final credits. Levy wrote the words and music.

Everyone has a favorite SCTV skit featuring O’Hara. Mine is the high-school quiz show High Q, where she plays student Margaret Meehan, whose perpetual gun-jumping frustrates host Alex Trebel – Levy again – into a rage.
