Mr. Sunshine

"It was the most surreal experience of my life," Allison Janney says of dueting with five-time Grammy winner James Taylor for Mr. Sunshine's March 16 episode. The singer guest stars on the ABC comedy as Billy, the ex-husband of Janney's Crystal. Turns out the exes had a lounge act and reunite to sing Leon Russell's "A Song For You," which Janney says "is probably one of the hardest songs to sing for someone who hadn't sung since stepping off the 9 to 5 stage over a year earlier."

The pair had to do about fifteen takes on a smokey nightclub set in front of co-star Matthew Perry. Janney, who missed some of the high notes, rates her performance as "okay." But by the next day, "I'd literally lost my voice and couldn't talk."
