The frontman of hit West Australian band Spacey Jane, Caleb Harper, has played in front of plenty of big crowds.
But he has never bowled a cricket ball in front of a packed Optus Stadium.
That will change on Boxing Day, with the top Aussie indie artist locked in to deliver the celebrity first ball before Perth Scorchers face Brisbane Heat on Thursday night.
“Seam up. 145km/h. Swinging,” Harper joked when asked what fans can expect.
