The Doobie Brothers

The album cover may feature more Frito Bandito mustaches than the Mexican Revolution, but the Doobies' only No. 1 album completes their transition from boogie rock band to sleek yacht rockers. Michael McDonald's funky keyboard and mush-mouthed tenor take the spotlight and helped get the band plenty of play on radio. Songs like the title track, "What a Fool Believes" and "How Do the Fools Survive" fit into hedonist pool parties as well as child-friendly roller-rinks. And even though the Doobs often go down smooth, they find room for some of their old boogie rocking ways on "Don't Stop to Watch the Wheels."
