The first that comes to my mind is Loudon Wainwright, father of Rufus Wainwright. I don't have any of his stuff, either.

wait i own kerplunk
I like Greenday, too, but never bought an album.
there is really no need to you hear them all the time (even old stuff) mp3s are plentiful and someone else always seems to have some if you need to borrow it. That being said "Waiting" is my favorite Greenday song
I have tons of Green Day if you want some.
