RIP Michael Brewer, whose “One Toke Over the Line” was a hippie anthem.

Michael Brewer, half of the folk-rock duo Brewer & Shipley, who scored an unlikely Top 10 hit in 1971 with “One Toke Over the Line” — one of the most overt pop odes to marijuana of the hippie era and presumably the only one to be performed on the squeaky-clean “Lawrence Welk Show” — died on Tuesday at his home near Branson, Mo.
