Alex Kapranos says Ross was his usual self at the recording
Franz Ferdinand say they had no reservations about appearing on Jonathan Ross' chat show after his involvement in the prank phone row.
The band said they were excited to appear on the first episode of Friday Night With Jonathan Ross after the host's three month suspension.
Alex Kapranos told Newsbeat: "He's a funny guy. No matter what anybody else has been saying about it at all."
Ross repeated his apology while filming and said he would be "more aware".
Kapranos said that the band had been out of the country when Ross was suspended after making a series of prank calls to Andrew Sachs on Russell Brand's Radio 2 show.
Ross apologises on return to TV
Kapranos said: "I didn't realise it was so much of a hassle because we were touring round the States when it all broke.
"So we came back to the UK and it was like, 'Whoah, what's been going on?' Front page news for 11 days or something like that. It was crazy.
"Despite all that he's still a really funny guy and he gets great guests on the show. Today was Lee Evans, Stephen Fry and Tom Cruise. It's pretty spectacular."
Kapranos described the atmosphere backstage as "relaxed" and the other guests as "really charming."
Describing Ross himself, Kapranos thought the host seemed his usual self: "He didn't seem toned down. He seemed very at ease and relaxed.
"I think everybody was aware of the situation. He was himself. Which is what you wanted to see, I think. You don't want to see a watered-down version of his personality."
