The lead singer of Powderfinger has been told to stick to singing his songs after he went on an anti-Trump tirade mid-show.

Bernard Fanning was performing at his opening show of his Tea & Sympathy 20th anniversary tour on Wednesday night when he was interrupted by a member in the audience.

During his gig at Sydney’s State Theatre, Fanning was preparing to perform a cover of the Simon and Garfunkel track, Kathy’s Song.

However, before he was ready to roll, he had his own political remark he had to get off his chest.

“I was thinking about this today … I accidentally was watching the news and the f***wit pumpkin came on and started yelling at everybody and it made me think about how we’re so bombarded by information,” the 56-year-old remarked.

A fan in the crowd sounded annoyed by Fanning’s comment and chimed in.

“We’re here for the music, mate!”

Fanning hit back: “I can’t hear you mate … what are you saying?”

“And if you don’t want me to talk, that’s ok. You can get f***ed.

“So, anyway as I was saying, we’re so bombarded by information you know, and it’s so hard to sort through all of it, and decide what you really think, and the thing that I came to was that, for me, it always comes back to music and art, (it) always brings me comfort.”

The crowd was heard erupting in cheers throughout Fanning’s exchange with the fan.

Fanning’s next show is on Friday at Adelaide’s Thebarton Theatre.

The Brisbane-born artist is known for his smash hit Wish You Well, along with Powderfinger chart-toppers, My Happiness, These Days, (Baby I’ve Got You) On My Mind and Burn Your Name.
