Dueling piano players, hit makers of the karaoke leaderboard and all-out tribute bands rarely get their proper due in the limelight. But get ready for the latter musical misfits to enjoy cinematic comeuppance. The true life story of two down-on-their-luck musicians who perform in a Neil Diamond cover band in grunge-era Milwaukee, Craig Brewer’s Song Sung Blue (B+) is one of those movies they just don’t make anymore, the idealistic tale of two good but imperfect souls overcoming incredible odds to make amazing music and life together. A jubilant Hugh Jackman and a resplendent Kate Hudson co-star as Lightning & Thunder, two halves of a novelty act that doubles as an excuse for mutual burgeoning love interests. The film is unabashedly melodramatic and formulaic, and yet it still hits all the right notes to keep viewers deeply engaged. Hudson in particular is wonderful in her role, acting and singing her way through a crucible of challenges as a salt-of-the-earth everywoman. It’s a triumph for this popular actress. Brewer stages montages such as “Sweet Caroline,” “Play Me” and “Holly Holy” with gregarious gusto, with several standout montages mirroring stage life and behind the scenes travails. The film is the genuine article, with legitimately nice people being good to one another and lifting each other up in community. This is an enjoyable crowd pleaser successfully turning on the heart lights of communal multiplex patrons everywhere.
