If you wanted to catch Jug and Sonny in Chicago circa 1961, you took your chances (esp. if you were a white boy) and headed to McKie's Show Lounge at 63rd and Cottage Grove. No risk was too great to deny the ultimate reward--the experience of being seated literally inches from the Selmer Mark 6's of the South Side's two great tenor troubadors, miraculously squeezed together on a postage-stamp bandstand along with a drummer and Hammond B-3 player just across the bar (patrons would reach across and shake the hand of a triumphant soloist, or pass along a drink to the usually obliging Sonny).
As good as this album is, it comes up just a trifle short because of the use of an acoustic piano, at the time an artifact of the recording studio (though Sonny would gravitate more and more toward piano players as the sixties closed out). For the "ultimate trip" the album you want is the one with Jug and Sonny plus Donald Patterson on organ, especially the side that includes tunes like "Bye Bye Blackbird," "Why Was I Born," "Long Ago and Far Away," and "Walkin'". At one time, that side was included with this one as part of a two-fer album called "Prime Cuts." It might take some trouble to find, but it's well worth the hunt.
