HONOLULU -- Champion Manny Pacquiao has been dominant draw to see his fighting skills, but apparently he is not as in demand for his singing skills.

The welterweight champion was scheduled to hold a concert at the Waikiki Shell on Sunday night, but the organizers on Tuesday announced they will cancel it because of poor ticket sales.

The fighter from the Philippines defeated Joshua Clottey in Texas Stadium this past weekend in front of more than 50,000 spectators.

Island Fire Productions said it hopes to renegotiate another concert appearance. The company plans to issue refunds to ticketholders starting on Thursday where they made their purchases.
