After Audra McDonald recently teased us with a quick rendition of "I'll Fly Away" on The Good Fight, her co-star and fellow Tony Award winner Christine Baranski is joining in on finally showing off her pipes on the legal drama. In the clip below from an upcoming episode of the CBS All Access series, the two—as Liz Reddick and Diane Lockhart—duet on Prince's "Raspberry Beret."

"I thought you were more of the Renée Fleming type," a surprised Liz tells Diane. (Of course, McDonald herself is ironically more a "Renée Fleming type.")

The moment, unveiled by E! News, is the latest in fleeting musical moments featured in the Good Wife spinoff, which regularly highlights stages favorites due to its production in New York (recent guest stars have included Katie Finneran, Kate Shindle, Richard Kind, LaChanze, Michael Urie, and Deidre Goodwin).

McDonald will return to the Broadway stage later this year—though not to sing. The six-time Tony winner is set to star alongside Michael Shannon in Frankie and Johnny in the Clair De Lune. Performances begin May 4 at the Broadhurst Theatre.

The CBS All Access series airs on the streaming service on Thursdays.
