The singer, who's expected to tour the U.S. next year, doesn't want a lavish affair when he marries Kenny Goss

George Michael, who recently announced his first tour in 15 years (including an American leg slated for 2007, a source tells PEOPLE), plans to marry partner Kenny Goss in a small ceremony – not an extravagant wedding like his rival, Elton John’s.

“I think we’ll just do the formal legal thing and then we’ll have a party,” Michael told the audience of the British talk show Parkinson last weekend. “But no one’s going to be getting into a dress! Neither of us has the body for it, you know.”

Same-sex couples have been legally able to form civil partnerships in Britain since Dec. 21, 2005 – the same day Elton John married partner David Furnish in a brief service followed by a $2 million, 600-guest reception.

Of marrying Goss, Michael said, “I think from a legal point of view it’s essential to have the same safeguards that straight couples have. We’ve been together for 10 years. I think we’re entitled to that.”

Michael has some other reasons to be optimistic these days: Tickets to his 25 Live European tour, which kicks off in Spain on September 27, sold out in three hours when they went on sale on April 23.

“He’s thrilled. Just over the moon,” says a source close to the singer.

Additionally, an as-yet-unannounced American leg of the tour is expected to start next year, with dates and details to be revealed in the near future, the source tells PEOPLE.

Despite an arrest for drug possession in February and a car crash last month, Michael has been buoyed by the renewed interest in his music – and his happy love life.

“I’ve felt good for the last year or so,” Michael said. “I’ve felt great, which is why I decided to tour.”

Besides, Michael hopes touring will change his relationship with the media. “If I can establish a live rapport with an audience again, I might not have to worry about releasing singles and putting myself in the way of the media the whole time.”
