A small label plans to release an album of material recorded by 'American Idol' runner-up Adam Lambert this summer - in advance of Lambert's much anticipated major label debut. The singer claims the material was culled from studio tracks for which he simply provided vocals, but Hi-Fi Recordings/Wilshire Records disagrees, saying that Lambert co-wrote a number of the songs on the album.

The AP reported that Lambert's statement read: "I was hired as a studio singer to lend my vocals to tracks written by someone else ... I was broke at the time and this was my chance to make a few bucks."

The indie label shot back with their own statement, writing, "Adam is now enjoying the success that he and Wilshire Records hoped for. However, he is now represented by high-profile companies who released a statement in Adam's name saying the songs on 'On With the Show' were recorded four years ago and Adam only contributed vocals. This is simply not true.

"The songs were recorded in a professional recording studio with top notch musicians and producers since the music was always meant to be released. Of the 11 songs that will appear on the album, 'On With the Show,' Adam co-wrote eight with Monte Pittman (Madonna's guitar player)."

TMZ has posted an internal memo from Lambert's former label, which indicates the 'Idol' singer as co-writer on the majority of tracks on the album.

Wilshire records assures Lambert's fans, "As co-writer and performer, Adam will receive significant royalties just as any superstar artist would. He has the chance, finally, to make a fortune for his work - definitely more with this album than through a major label deal.

"This pre-Idol work is a fantastic representation of who Adam is and what inspired him during the months before he became famous."
