The film "Song Sung Blue" tells the true story of Mike and Claire Sardina, a Midwest-based Neil Diamond tribute act. Portrayed by Hugh Jackman and Oscar-nominated Kate Hudson, the movie explores the couple's unconventional journey from forming their musical duo to achieving unexpected success.

Mike Sardina is depicted as a Vietnam veteran who has struggled with alcoholism but has largely overcome his addiction. He meets Claire, a singer who inspires him to create a Neil Diamond tribute experience known as Lightning & Thunder. As their partnership develops both professionally and personally, the duo eventually marries and gains recognition, including the opportunity to open for the rock band Pearl Jam early in their rise.

The narrative highlights how dreams can sometimes transcend harsh realities; however, the couple's story is not without its challenges. Real-life struggles intrude on their aspirations in significant ways, presenting obstacles that test their resilience. Jackman and Hudson, both experienced musical performers, lend authenticity to their on-screen performances, particularly in renditions of songs like "Sweet Caroline."

Additionally, the cast includes Michael Imperioli, known for his role in "The Sopranos," who plays a Buddy Holly impersonator joining Lightning & Thunder. His character adds another layer to the film’s depiction of tribute acts and their subculture.

Overall, "Song Sung Blue" balances its potentially sentimental premise with strong performances and a grounded portrayal of pursuing dreams amid adversity.
