The Guess Who helped shape the soundtrack of the late ’60s and early ’70s, with the unmistakable vocal timbre of Burton Cummings providing the power and emotion behind songs such as “Undun, “American Woman,” “Hand

Me Down World” and the band’s debut hit, “These Eyes.” It would have been highly unusual to tune into an album-oriented FM radio station during the band’s heyday and not hear Cummings’ baritone in sing-along anthem mode (“Share the Land”) or soaring over Guess Who harmonies (“No Time”).

Cummings would enjoy an entirely satisfying solo career after he left the band in 1975, hitting the American charts with “Stand Tall” in 1976. And at 68, he shows no sign of slowing down, maintaining a steady live performance schedule. Center stage at his keyboard, Cummings sings lyrics that have become timeless to his fans, and throws in a few favorite covers. In recent years, shows have included Buddy Holly’s “Not Fade Away” and Kurt Weill’s “Mack the Knife,” with Cummings maintaining a rapport with the audience through song introductions and an easygoing stage presence.

Multi-instrumentalist Cummings—his flute solo on “Undun” is a particularly notable set highlight—is backed by Toronto’s Carpet Frogs, featuring bassist Jeff Jones, who may be familiar to fans of Red Rider (“Lunatic Fringe” and “Human Race”) and Ocean (“Put Your Hand in the Hand”).
