Texas Wild Flower Comparison

Trying to recreate a song my Brother John Jackson wrote in 1971. It was recorded at Studio One in Atlanta Georgia with Rob Boykin & John Jackson but I have never heard it All I have is his handwritten Lyric Sheet with some notes and some pics. The song is about John's girlfriend Marsha who ended up marring his friend Rob Boykin. In the song it says John got her pregnant! There may be a Little Juke out there that doesn't know it.... would be 50 something now.
