Zoomers of a certain vintage will remember this.
That is American singer Roy Head on “Shindig” singing his number two hit, “Treat Her Right.”  For a time, in 1965, the song was just behind the Beatles number one hit “Yesterday” on the Billboard Charts.
Over a 50-year music career, Head recorded Blue Eyed Soul, R & B, Country and Rock-a-Billy music.
Roy Head has died at the age of 79.
