Hello
Wild Mutha is really easy, almost the same structure as Ape Man by The Kinks, Larry may use some faancy chord variations but these are the basics:
intro: E D A E
verse: A E
chorus: D A F#m D E A E
bridge: same as verse and chorus
A skill to learn for rock and roll is the hammer on with the little finger. Make a bar-chord/powerchord shape with two fingers and the hammer on and off with the little finger. Easy when you know how. The lead part is a mixture of simple rock n roll lead with a twist of surf whereby you drench the guitar in reverb and play one note leads. Its really tricky to do consistently well.

A bit trickier, the lead makes it seem difficult but it's actually a really simple song:
Verse/chorus: D E D E A
Break: A C D
Lead: D D C D D F D F D F D C D (starts on A string 5th Fret)
Bridge: same as verse/chorus
enjoy :D
