From Playbill video:
A Tony winner for her turn in "Hallelujah, Baby!," Leslie Uggams has had a long and storied career on the Broadway stage and in Hollywood. In Playbill's first episode of "Seth's Broadway Chatterbox," host Seth Rudetsky chooses to focus a rare less-than-stellar Uggams moment — an incident that had faded into obscurity until brought to newfound infamy via YouTube. Uggams tells the story of how she almost had to invent a new language to cover the "slipped" lyrics during a live performance of Rodgers and Hammerstein's "June is Bustin' Out All Over."
