So I was watching a movie from the '70s called Ben...Michalel Jackson made the song "Ben" famous. A Google search shows it having these chords:

G, D, B7, F, E, Am, C, D7

Well, I am still SUPER new and am learning chords, but I do not know many... but cant I play this song one note at a time? no chords? if so, what single note whould B7 be, what single note would Am be (A?) what single note would D7 be?

Sorry for a totally NOOB question but just curious. Thank you all!
