Oasis is back at No. 1 on the U.K. album chart, as its fifth studio set "Heathen Chemistry" (Big Brother) ousted Eminem's "The Eminem Show" (Interscope/Polydor) from the top spot yesterday (July 7). Meanwhile, the King still reigns on the singles chart, where "A Little Less Conversation" by Elvis Vs. JXL (RCA) remained on top for a fourth week, despite the label's controversial decision to stop pressing the single.
