What the Hell Happened to Blood, Sweat & Tears?

"What the Hell Happened to Blood, Sweat & Tears?" is a 2023 documentary film about American band Blood, Sweat & Tears touring in mid-1970 through several Eastern Bloc countries during the Cold War. The film explores how the band's reputation suffered after this trip, particularly due to protests from fans who had been in agreement with the band's anti–Vietnam war stance but felt betrayed. Band members David Clayton-Thomas and Bobby Colomby reveal a secret story of being blackmailed by the US State Department into making the trip for Clayton-Thomas' Canadian lead singer status; The filmmakers incorporated visual materials, including little-seen concert footage and press conferences, from a failed 1970 documentary project that never reached its intended audience.
