Angus Young has hailed Axl Rose after the Guns N' Roses mainman stepped in to front AC/DC to help the veterans complete their current tour.
Rose threw his name in the hat for the AC/DC frontman role after Brian Johnson was forced to retire due to fears about his long term hearing.
To date all reviews and live reaction to the new AC/DC line-up has been overhwhelmingly positive since his maiden appearance in Lisbon on May 7.
Now in an interview with Germany's NDR.de Angus says: "He's doing very well, and it's very good that… I mean, under the situation that we had, it was very good that he volunteered and said, 'Hey, if I can help, let me try.' So he's been very good. And he had to learn a lot of songs very quickly, and he's done a great job."
In additon to a run of ten European dates, increased to 11 with a new German date added, Axl is also confirmed to continue his run as 'a guest vocalist' for the band's postponed ten dates of their recent US tour.
AC/DC bassist Cliff Williams continues: "Axl has done a fabulous job. And he's almost out of his chair now. He's mobile, and he's enjoying himself. It's been really good."
Added Angus: "His leg's repairing, so each show we've been doing he's been getting up and moving around a lot more. So it adds more to the show. We were committed to finishing this tour, so that's been our main goal, and Axl helping us.
"I know he's very excited; he keeps saying, can he do more? But we don't really know at the end how we will [go from here]. But we wanna get this tour, which we were committed to doing, we wanna finish it."
Axl, who is also hitting the road this summer with his reunited Guns N' Roses line-up, has gone on record to express his desire to extend his stay with AC/DC long-term.
Recentky he told the BBC: ""There's makeup dates in the States, and if I don't get throw out before then, I'm looking forward to doing [them]. I think after that, it's about what they wanna do. I'm in if they want me in, and we'll sort it out, but right now that's getting ahead of ourselves with everything else that's on the table."
Meanwhile, Brian Johnson has this week insisted he left AC/DC on good terms with the band revealing their was no ulterior motive for hsi departure.
In an interview this week he explains to Sirus XM that his hearing loss was caused by 'fluid crystals' in his ear: "'I was getting worried because my right ear is my good ear,' he said, adding that his left ear is already 'just about totally deaf' from a New York motor racing event eight years years ago.
'When we got (to Australia), that’s when Dr. Chang found out that the fluids had crystallised and had been eating away at my ear,' he began.
'So my good ear, I lost I don’t know what percentage - but it was enough to make things very difficult. So they worked on me,' concluded Brian.
Johnson was diagnosed by an ENT specialist in Australia, who found the fluids had 'crystallised' and were 'eating away' at Brian's ear, leaving him losing his hearing and facing possible total hearing loss.
The 68-year-old also rubbished earlier suggestions he had been 'fired' from the band or 'forced out', insisting there was no alternative but to hand up his mic.
'The boys saw the charts. I’d been getting checked regularly,' he continues. 'And they saw there was a massive dip and if I’d have kept on going, there was a possibility I would never hear again.
'Angus and Cliff just said, "Johnno, you’ve got to think of your health.'"
'And everybody else said, "Brian, your health comes first. You’ve done a whole year on the road. You’ve done everything. We want to finish."
'And that’s what they did. It’s simple. What people don’t understand is it is what it is,' he adds.
