This is an interesting country rocker on Bill Glore's Glo-Lite record label from Memphis, Tennessee. It sounds it was recorded in the 1970s, although a late 1960s recording date seems also possible since Glore established Glo-Lite in 1968 and this was one of the earlier releases.
Although the record label shows an adress as of 4081 Jackson in Memphis, I believe it was recorded at 625 Chelsea Avenue, where the Glo-Lite studio was located. No information on Travis Lee can be found. There was a Travis Lee on Cal State Music, a label active in the early 1970s in Santa Monica, California. I doubt it is the same singer.
The flip side to "I Wish the Sun Would Shine" is a country ballad, "Then I'll Go." More info on Glo-Lite Records can be found here.
