A week after Patton’s Third Army liberated Buchenwald, on April 19, 1945, the inmates gave a concert for the soldiers who had freed them. Fourteen Czech, German, Dutch, Belgian, and French musicians made up the band. The Simon Wiesenthal Center in Los Angeles has the fading typed program on exhibit: There were sax, brass, and rhythm sections, and a sole vocalist—a Frenchman, Robert Widerman, who sang “In the Mood,” “A Tisket, A Tasket,” and “Honeysuckle Rose.” He also performed both roles in a Mickey and Minnie Mouse skit of his own creation, which had been a hit with the Nazis and kapos.
“We performed on the stage, in our striped uniforms, exhilarated by our new freedom, and gave the greatest show of our lives which hundreds of GIs and inmates applauded and shouted,” he noted in his memoirs. They closed the set with a “walloping version of ‘Tiger Rag.’”
A few weeks later, back home in Paris, the boyish but indefatigable Widerman, age 19, opened at the legendary Olympia on the Boulevard des Capucines, then one of the many Parisian venues requisitioned for American soldiers’ entertainment. He was the fourth on the bill, in an unenviable slot right after a performing dog act that always thrilled audiences. His first number was “Flat Foot Floogie,” followed by “Daisy Venez Avec Moi.” The audience wasn’t buying it. He was distraught at the perfunctory applause. “I had two more numbers to do, and I was having flop-sweat. I didn’t understand—they loved me in Buchenwald!”
The singer, who had changed his surname to Clary, took gigs all over Paris, working full time, dancing with socialites and prostitutes (“I remember one in particular. She was tall and looked like Joan Crawford … a very good jitterbugger. We had a ball on the dance floor.”) He performed in blackface. He made friends with Charles Aznavour. He relocated to the south of France and worked around the clock.
