Benson opened his set with a tribute to BB King as well as to Rachelle Farrell, whom he followed in the evening lineup. “They’re gonna’ be cleaning the paint off the floor for weeks,” Benson said of Ferrell’s set, and then lit into his own pyrotechnics.  The full-house crowd cheered him on through the midnight hour and cried for more when he closed with a lively rendition of “On Broadway.”
