Thru the Years is a compilation album of music by John Mayall released in October 1971 by Decca Records in the U.K. and London Records in the U.S.A. The album was the second compilation to be issued by Decca/London with Mayall's blessing, although his contract with them had ceased. It features a mixture of previously unissued songs or non-album tracks that had only been released as singles. The album reached No. 164 on the Billboard 200. It was re-released by Deram on CD in 1990.
