Sir Paul McCartney agreed to put his new single in Lexus commercials, due to their new line of hybrid vehicles.

McCartney, who's an environmental and animal rights activist, agreed his new song "Fine Line," the lead track from the ex-Beatle's album "Chaos and Creation in the Backyard," to appear in spots for Lexus' new hybrid vehicles.

'Anyone who`s making a hybrid and is talking about making more of their models environmentally friendly is something I can get behind,' says McCartney, who doesn't appear in the ads himself.

'When it was put to me that they wanted to sponsor the tour and when I actually saw the car and saw what it was all about, I said `Yeah, sure, that`s something I can definitely get behind. It beats beer commercials.'

McCartney's new album, titled Chaos and Creation in the Backyard, was released in September 2005, coinciding with an anticipated U.S. tour. Longtime Radiohead collaborator Nigel Godrich, suggested to McCartney by producer George Martin, produced the album, recorded in London and Los Angeles over the past two years.

According to McCartney's official Web site, the 13-track album is "a mix of up-tempo piano driven McCartney instant classics such as "Fine Line" and "Promise To You Girl," and more introspective, darker tracks such as "At The Mercy", "Too Much Rain" and "Riding To Vanity Fair".

There's also "Jenny Wren", which Paul describes as "daughter of Blackbird", as well as "Follow Me", which McCartney debuted with at The Glastonbury Festival, while on his '04 Summer European Tour. "Fine Line" was released as the first single on August 29, 2005.
