The Troubadour Reunion Tour, starring co-headliners James Taylor and Carole King, is this week's top-grossing tour with more than $23 million in box office grosses reported from 13 venues. All were arenas except for the Hollywood Bowl where the veteran entertainers played to 51,168 fans during three performances (May 13-15). The $3.5 million in sold tickets at the Los Angeles amphitheater is the tour's top reported gross since its March 26 kick-off in Australia. Two shows at Boston's TD Garden also surpassed the $3 million mark in ticket sales. The 19,600-seat arena hosted the tour for two nights (June 19-20) with a combined attendance of 30,851 from both shows. Other venues with two-show stints were Verizon Center in Washington, D.C. (June 8, 23), Philadelphia's Wachovia Center (June 10, 22) and the Mohegan Sun Arena in Uncasville, Conn. (June 12-13).

At Sheffield Arena on May 6 the Canadian singer began a six-market run through the U.K. that produced £3.4 million in sold tickets. The top attendance came from the Manchester Evening News Arena with a crowd of 14,042 for one performance on May 9.
