About the title:
"Welcome Back" is a popular record that was the theme song of the 1970s American television sitcom, Welcome Back, Kotter. Written and recorded by former Lovin' Spoonful frontman John Sebastian, it reached #1 on the Billboard Hot 100 chart for one week in May 1976 after only five weeks on the chart, and also topped the adult contemporary chart.[1] (The show itself had become an instant ratings success upon its premiere the previous fall.) It also reached #93 on the country chart.
