Hugh Jackman and Kate Hudson team up with director Craig Brewer for “Song Sung Blue,” an emotional drama drawn from the real-life story of Milwaukee’s Neil Diamond tribute band Lightning and Thunder.

In my critique, I characterized the film as a “heartwarming flick and a poignant tearjerker,” emphasizing its exploration of lofty aspirations, profound losses, and the therapeutic essence of music. During my discussion with Jackman, Hudson, and Brewer, we naturally explored the influence of karaoke.

In the film, Jackman and Hudson take to various stages, but two karaoke sequences stood out to me. The celebrated actors talked about these scenes and recounted personal stories, including Hudson’s performance for Quincy Jones and a rendition of “Summer Love” from “Grease” featuring John Travolta and Jackman, with Jackman humorously adopting Sandy’s part because of his Australian background.

Brewer conveyed his enthusiasm for karaoke both on-screen and off, articulating why this style of expression is so resonant and relatable.

“Song Sung Blue” debuts in theaters on Dec. 25.
