This one of The Earlybirds songs , It is the rythm guitar part but the lead guitar 
also does this!!! =) 

If you wanna figure out the solos its notes from the Pentatonic scale so its easy as! 

Listen to the song to get the rythm (its to hard to tab haha) 

Verse / chrous / intro : Am , D , Am , D 
When lead guitar is doing solos , Rythm guitar palm mutes (pm): Am 

There you are The Earlybirds fans!!! enjoy!! 

THNAKS!
