The pleasure of these joint appearances for me is to see how much utter joy Bonnie Raitt has during them, not just being able to perform with her dad, but mainly to bring to her father the attention of her own fans and let them know that in his prime he was perhaps has big a Broadway star as she was in her field. But there's pleasure too in seeing how much he enjoys to have some limelight again, while reveling in daughter's fame.
This song, "Hey, There," comes from one of his Broadway hits, The Pajama Game, written by Richard Adler and Jerry Ross. And it nicely starts with a solo by the father portion of the equation that leads into an sweet walk-on introduction. And then eventually into Bonnie Raiitt's own solo of one of her own big hits.
