U2 frontman Bono and guitarist The Edge enjoyed themselves while taping a segment of Elvis Costello's CTV show Spectacle -- actually the Season 2 premiere which airs tonight -- at the Masonic Temple in Toronto back in mid-September.

Even if the venue supposedly has ghosts.

"To be in that theatre was such a magic thing," said Bono in a Canadian newspaper exclusive while the Irish band was in Toronto for two sold-out shows at Rogers Centre.

"Although somebody was telling me, 'You know on the fifth floor, it's haunted.' I said, 'Well, if it was, after tonight (U2's taping), it's ain't going to be. We're going to chase those demons away.' "

The Edge said he's a fan of both Spectacle's variety format that includes interview and performance and its host.

"To help out Elvis Costello's new show, it's such a great idea and I think he's absolutely the right man for that particular show," the guitarist said.
