The near-capacity crowd at the National Concert Hall of Wales is a prelude to the record-tying audience expected at Principality Stadium on Saturday where nearly 80,000 fans will match boxing’s all-time indoor attendance record, initially set in 2017 in Joshua’s title defense against Carlos Takam at the same venue.
