Kenny and the Kasuals were a band from Dallas who were active mostly during the 1960s. Although this song is straight-ahead rock & roll, some of their original songs began using elements that would later come to be known as psychedelic rock, and they are considered a pioneering band in that genre.
I read about them in a book called The Acid Trip, which was all about acid rock bands. It was compiled by someone who lived in England and the book had a very amateurish look but was full of information, and had one whole chapter devoted to acid rock bands from Texas. Back in 80s, I was a very good customer of the local book & record store, and the manager there sometimes went to extra effort for me to find some obscure stuff. One day I walked in and he said, "Hey, you asked me about these guys one time. You still want to buy this?" and he showed me two albums by them. I bought them.
During the time they were active, they cut a bunch of singles and only one album, which was a live album. Later on, someone took all their singles and made a couple of "albums," which is what I have.
They had a very devoted following and were expected to make a big breakthrough and get super famous, and then their lead singer--Kenny Daniel--got drafted. By the time he returned to the States, the window of opportunity had passed, but he got some of the group back together and toured as an opening act for a while for people like Iggy Pop and the Boomtown Rats. Some of them might still be performing at oldies shows, I'm not sure.
