Although the series finale of Will & Grace was a bit disappointing as a whole, one bright spot was a nice little duet between characters Karen Walker (Megan Mullally) and Jack McFarland (Sean Hayes). It happened towards the end of the show, when we fast forward about 20 years and find Jack and Karen living together. With Jack at the piano, they perform a nice rendition of Unforgettable. It was a pleasant little moment that showcased the other talents of both Mullally and McFarland.

Mullally, whose normal voice isn't as high or whiny as Karen's, has been a professional singer for some time. Before joining the cast of Will & Grace back in 1998 she spent several years on Broadway in the productions of Grease and How to Succeed in Business Without Even Trying. She is also a lead singer for the Los Angeles-based band The Supreme Music Program. In 2002, Mullally and her band produced an album, Big as a Berry, which featured covers to such songs as Ode to Billie Joe and Danny Boy.

More information on Mullally and her band can be found at her official website. There is also a link for her new talk show, which is premiering this September. Perhaps we will hear more of Mullally's singing then.
