Like many artists in the mid-'60s who didn't hitch their musical wagon to any one particular post, the duo of concocted a hearty gumbo made up of strutting soul, sticky bubblegum, mildly trippy psychedelia, some down-home country, and lots of good old rock & roll. The Dallas-based pair sounded like a less polished , or a more Earth-bound , with -- known as on her driver's license -- sporting a booming, scene-stealing voice and providing the plain-spoken, mock rejoinders. Working with ace songwriter , who wrote "The Letter" for the like-minded , and some fine producers, cranked out a bunch of singles and two albums over their short run. already issued a collection of their work in 2006; here, the label presents it again in case anyone missed it the first time or just wanted the duo's output boiled down to the singles. The best of the tracks are top-notch radio groovers: "Do It Again a Little Bit Slower" is their main claim to fame, but others, especially the rollicking " Dr. Jon (The Medicine Man)" and the plaintive rocker "Can't Make It with You," are nearly as good. The blend of their voices isn't always smooth and the songs aren't always the cleverest, but they put them across with plenty of showy oomph. No amount of effort can save "There's an American Flag on the Moon" though; it's a terrible novelty song that's about as square as pop got in the late '60s. Luckily, there are enough good tunes that come before it to help ease the pain that giving it an accidental hearing might cause. Instead of making that mistake, double back and give "Do It Again" another spin. Its amazing blend of elevator-slick harmonies, "Cool Jerk" piano breaks, 's soaring backing vocals, and the finger-snapping rhythms brings to mind a Madison Ave. version of doing a hip catsup commercial. It's kind of weird and kind of wonderful, and the same goes for the rest of the set. is a breezy and highly enjoyable document of a strange and interesting time in music history. may be just a footnote, but they are one worth checking out and not skipping over. ~ Tim Sendra
