Funnyman Steve Martin thrilled the audience during a concert with the Steep Canyon Rangers by inviting fellow actor Alec Baldwin to join him onstage.
The Parenthood star appeared with the bluegrass band at a concert in East Hampton, New York on Saturday (02Jul11) and had an extra-special treat for revellers.
He stopped the performance to introduce Baldwin, who was in the audience, and the 30 Rock star then joined Martin onstage for a rendition of Jubilation Day, a track Martin recorded on his Rare Bird Alert album.
According to the New York Daily News, Martin told the audience, "I'd like to introduce one of the best bass singers I know - and that's without the 'b'!"
