The flip side "Shook, Shimmy, Shake" is toned down a bit, but still quite funky AND cool. The organ style is reminiscent of the Jamaican keys legend Jackie Mittoo and even the horns have a slight ska rhythm to them (it is no surprise that Island records took their ska/soul legend Jackie Edwards and utilized a Wynder K. Frog song "Oh Mary" as his backing track for his "vocal" version of the same number). Any "ska" detection on this tune is of course because it's an instrumental cover of a track by the ska/rocksteady legend Owen Gray previously issued on the label in 1965 as WI 252.
