A war of words has erupted over a live television performance featuring Kiwi legend Neil Finn and alt-country singer Ryan Adams.
The pair, alongside American folk singer Janis Ian, were performing during an episode of BBC's Songwriters' Circle, a show which sees singers sitting together on a stage helping outon each other's songs.
But Adams has gone online to vent his frustration at Finn and Ian for playing guitar during his songs, thevine.com.au reported.
Adams also defended his decision not to help out on backing vocals on Finn's encore Fall at Your Feet.
"I was never asked to play on that song. It was not mandatory to play on each others songs and I was respectful to both Neil and Janis by way of listening and enjoying their tunes," he said in a blog.
"They played over almost every song I played. I found that odd and it nearly derailed Invisible Riverside."
Adams said things got "ugly" when Finn started yelling to let him know he wasn't happy with his lack of participation.
"My experience was we had a nice time till Neil started yelling at people on stage. That was when things got ugly. And, I'm sorry, I don't care who you are. If you yell at me, I'm not going to be nice back. Certainly not going to play after that," Adams said.
Finn had only this to say on Twitter: "Well Songwriters' Circle on BBC will be interesting, watch out for lovely backing vocals on Fall at Your Feet from Ryan."
Ian also joined the fray online, saying she'd never seen a show "go south" like that before.
"I'm not sure what (Adams') problem was, but he would not sing the part he'd sung so beautifully in rehearsal - in fact, he would not sing at all.
"I have to say that in 45 years as a professional performer, I haven't seen that kind of behaviour before."
