Heavy Hitters is a 2005 album of cover songs by the Michael Schenker Group. Originally planned by Schenker as a collection of covers featuring himself and a "revolving all-star cast of guest musicians," the album was labeled and marketed as an MSG album, with the result that Schenker received only a flat fee.In 2007, it was re-released as a Michael Schenker solo album under the title Doctor Doctor: The Kulick Sessions and included 4 additional tracks (1-2 and 13-14).
