I like this photo of the Invertebrates (or Inverebrates, but I think the Baytown Sun spelled the name wrong) in their early psychedelic shirts. This article ran in April, 1967.

Members were Colby Tipton, lead guitar; Rickey Glover, drums; and Bill Badeaux on bass, students at Cedar Bayou Junior School in Baytown, Texas, and managed by Larry Snderli.

Another group with no recordings that I know of.
