Act Naturally was a #1 country hit for Buck Owens in 1963.  The Beatles covered the song in 1965.  It was the B-side to Yesterday.

It’s basically a three-chord song with one bonus chord, the II7 (two-seven).  Songs with a basic three-chord structure and one cameo chord are a great way to train your ears to hear chords other than the I-IV-V7.

The video is in the key of G.  Let your ears figure out where the band is going to the IV (C) and the V (D) and when the II7 (A7) comes around at and I can play the part…your ears will scream with delight with a bonus chord being introduced into the progression.  Another I-IV-V7 song where the II7 makes the same sort of cameo appearance is Hank Williams’ Hey, Good Lookin’.  Have fun!
