At the end of "Planes, Trains and Automobiles," it hits Steve Martin's family man/ad exec character that his accidental traveling companion, a maddening but lovable goofball played by John Candy, literally doesn't have a home — that he just stays on the road like a lonely ghost.

I'm wondering if Bob Dylan doesn't have a home, either. The 75-year-old musical icon seems to travel continually, crisscrossing the country on one tour or another that brings him through the region with some frequency.

Well, he's at it again. Big Bob performs Sunday in the Grand Theater at Foxwoods. But before the skeptics raise their eyebrows wearily — perhaps, like myself, remembering too many recent Dylan shows in which he mumbled incomprehensibly and purposefully clowned-up the phrasing to ensure no fan could possibly know what song he was doing at any given point in the set — the Master is throwing a curveball.

First, he's offering a fine mix of hits and rarities and staying reasonably in time, enunciating lyrics, and sticking to the melodies. Second, following a recent spate of recordings in which he explores the Great American Songbook, the show will feature tunes like "All or Nothing at All," "Autumn Leaves" and "Why Try to Change Me Now." Reviews suggest he's doing a fine job in that context.

Most charmingly, Mavis Staples is opening. The soul legend, still in magnificent form and power — she's a year older than Dylan — will rock the hall with "I'll Take You There," "You Are Not Alone" and more from her own estimable catalog.

Bob Dylan with Mavis Staples, 7:30 p.m. Sunday, Grand Theater, Foxwoods, $70-$155; 1-800-200-2882.
