The Grass Roots are an American rock band that charted frequently between 1966 and 1975. It was originally the creation of Lou Adler and songwriting duo P. F. Sloan and Steve Barri. In their career, they achieved two gold albums, one gold single and charted singles a total of 21 times. Among their charting singles, they achieved Top 10 three times, Top 20 three times and Top 40 eight times. They have sold over twenty million records worldwide.
"I'd Wait a Million Years" charted 15 on the U.S. billboards in 1969. They had a lot of hits that I like but this probably is my favorite.
