From Summer 1963 here's the Beach Boy tune that came out first on the LP Surfer Girl - 'In My Room.' I practiced the harmonies over and over again singing to this one. I even told my mom I wanted a bass electric guitar because of this song.
The Beach Boys didn't invent the surf music but they sure made it famous. I think their harmony was what made them apart from other surf musicians like Jan and Dean, although Jan and Dean had their own moments.
