The Tyme of Day came from Irving, Texas, northwest of Dallas.

Members were:

Shelby Rogers – lead vocals and guitar
Bob Anderson – bass
Chris Rogers – drums

I found this photo of the group in the April 7, 1968 Irving Daily News, announcing their appearance at the Irving Teen-a-Go-Go with the Phase V, the Glenda Harris Dancers and emcee Ralph Baker.

The group traveled to Norman Petty’s studio in Clovis, New Mexico several times, cutting Shelby’s original songs “I Wanna Know” and “Persuade Me” in March of 1968, In June they cut another original, “Listen to What Is Never Said”.

Norman Petty added keyboards, and “Listen to What Is Never Said” / “I Wanna Know” saw release on Mercury 72861 in November, 1968. Besides the Rogers brothers, session notes from https://www.norvajakmusic.com/t-v.html list Larry Shaw on bass, though it appears Robert Anderson played bass at some sessions.

The group made two further sessions at the Petty studio, cutting “Am I Really Me” / “The Word ‘Because'” in August, 1968, / “You Don’t Want Me” and “The Game” in March of 1969. All of these have remained unreleased.
