"[The] excessive length means there's a lot of room for levity, too, including James Bay sitting in for a duet on "Blue No More," Mick Jagger's wailing harp on "You Did the Crime," and, best of all, a showdown with Keith Richards and Jeff Beck on "Cognac." Guy has some good moments on his own, of course - his guitar stings throughout and he can sell the house rocker "Guilty as Charged" with a vigor that belies his age - but the emphasis on ruminative tunes feels a bit heavy-handed. Maybe that's why the album ends with "Milking Muther for Ya," a minute-long dirty joke that punctuates the moody vibes of "End of the Line." Its very presence suggests that Buddy Guy would rather live it up while he still has a few good years left".
