I just bought a guitar today and i love love love green day (the reason i want to learn guitar!) and i want to start learning one of their songs right away…
Definitely "Brain Stew"… It’s 4 Repeated chords and the chorus is the same chords just different strumming! If you can kinda play acoustic. "Time of your life" isn’t too difficult. Strumming is a little awkward for beginners but it was one of the first acoustic songs I ever learned
