Singer Brian Wilson has urged his former band The Beach Boys to cancel a performance at a trophy-hunting convention where Donald Trump Jr will be one of the speakers.
Wilson said he and co-founder Al Jardine will have nothing to do with a show at the Safari Club International Convention in Reno, Nevada.
The 77-year-old tweeted saying it was a version of the band fronted by Mike Love, another founder, who owns the legal rights to The Beach Boys name.
Longtime member Bruce Johnston is also part of the band, who are set to appear at the convention on Wednesday.
Wilson said: "It has been brought to my attention that The Beach Boys touring group licensed by Mike Love are headlining at the Safari Club International Convention in Reno, Nevada."
Wilson said both he and Jardine are "emphatically opposed" to trophy hunting and asked fans to share a petition demanding The Beach Boys pull out.
According to the Safari Club's website, attendees will be able to shop for weapons and organise hunting trips.
Trump Jr, a longtime trophy-hunter, will deliver the keynote speech.
The petition demanding the Good Vibrations band pull out was launched by Eduardo Goncalves and has so far attracted more than 65,000 names.
Addressed to the band’s manager Elliott Lott, it asks: "Wouldn't it be nice if all the Beach Boys, stayed away from those who kill for fun?"
The petition threatens a boycott against the group.
The Beach Boys were founded in California in 1961 and sold hundreds of millions of records.
The Mirror is campaigning for an end to the bloodthirsty practice of trophy hunting, calling on the Government to ban the import of animals shot for pleasure.
Ministers are consulting until February 25 on whether trophy hunting imports should be outlawed.
