The male-female duo Jon & Robin released quite a few singles and two albums in the mid- to late '60s, showing off an engaging style that craftily a mix of bubblegummy pop/rock with a little psychedelia and Southern soul. "Do It Again a Little Bit Slower" was their most popular single with its likable male-female vocal tradeoffs, a "Cool Jerk"-like soul piano riff, and a fadeout that languorously stretched out the suggestive title phrase. Their other singles and LPs included some enjoyable material as well, devised with help from some of the best production and backup musician talent in their Dallas base.
