Simple guitar songs for beginning musician


I am a little better than a beginning guitar player. I would like suggestions for artists who use mostly simple guitar chords along with voice accompaniament. Songs and or artists who specialize in this genre would be appreciated. My idea is to improve my playing by playing and singing along. I hope this does not sound ridiculous.

Ellery, I know "The Lou Gehrig Story" by heart, But I can't find the chords anywhere. If I could "I'd be the luckiest man alive". Oh, you're talking about Black Sabbath. Their version is a distant second.
Gillian Welch - tab for most of the songs off of her "Revival" album can be found via a Google search. These are really cool songs that use common chords (you will need a capo)and simple structure. BTW, her sideman, David Rawlings, is a great guitarist.
Early Who. 1964 through "Tommy". "I Can't Explain" and "The Kids are Alright" are good easy ones. "I Can't Explain" has a rough patch in the middle, and I believe good tabs even mark the spots where you must literally bend the neck of the guitar backward to get the proper effect. Some of "Tommy" is easy, but other parts are quite difficult.

I second the opinion that you should avoid the Beatles or Dylan. Add Joni Mitchell to that list, as well. They are rough.
