US No. 1 with "Windy", and they reached No. 8 on the album chart with their first Warner Bros. album Insight Out. Their next single "Never My Love" also topped the charts in autumn 1967 (No. 2 Billboard, No. 1 Cashbox), and now ranks as one of the most successful of all Warner Bros. recordings—it became a radio staple and is now accredited by BMI as the second most-played song on US radio in the 20th century, surpassing both "Yesterday" by the Beatles and "Stand by Me" by Ben E. King. The group's 1968 Greatest Hits album was also a major hit, reaching No. 4 on the US album chart. In 1968, Mason Williams' instrumental composition "Classical Gas" reached No. 2 on the Billboard chart, selling more than a million copies, and Williams won three Grammys that year. Another notable Warner release from this period was Astral Weeks, the second solo album by Van Morrison (his first was on Bang), who signed with the label in 1968. Although it sold relatively poorly on its first release (and did not reach gold record status until 2001), it has been widely acclaimed by musicians and critics worldwide, has featured prominently on many "Best Albums of All Time" lists, and has remained in release almost continuously since 1968. During 1968, using the profits from Warner/Reprise, W7 purchased Atlantic Records for $17.5 million, including the label's valuable archive, its growing roster of new artists, and the services of its three renowned executives Jerry Wexler, Nesuhi Ertegun and Ahmet Ertegun. However, the purchase again caused rancor among the Warner/Reprise management, who were upset that their hard-won profits had been co-opted to buy Atlantic, and that Atlantic's executives were made large shareholders in Warner-Seven Arts—the deal gave the Ertegun brothers and Wexler between them 66,000 shares of Warner Bros.' common stock. On June 1, 1968, Billboard announced that Warner Bros. Records' star comedy performer Bill Cosby had turned down a five-year, US$3.5 million contract renewal offer, and would leave the label in August of that year to record for his own Tetragrammaton Records label. Just over one month later (July 13) Billboard reported on a major reorganization of the entire Warner-Seven Arts music division. Mike Maitland was promoted to Executive Vice-president of both the recorded music and publishing operations, and George Lee took over from Victor Blau as operational head of the recording division.
