Robert Plant says he's found some Led Zeppelin recordings that may see the light of day as bonus tracks when the band's catalog is re-released next year -- including a couple on which he's not singing.

Plant says, "I had a meeting with Jimmy [Page] and...there's some very interesting bits and pieces." But what he really wants to see released are the two songs with bassist John Paul Jones singing lead. He jokes that Page has offered him cars and a house as incentive not to release them.

Plant and his Sensational Space Shifters are holed up in Peter Gabriel's Real World Studios in Bath, England working on a new album.
