Hi all .... I was trying to figure out the chords of Bobby Vinton's song "Mr. Lonely". It's - I think - in B Mixolydian (5th mode of E major). The confusing part was (sorry if the lyrics are not perfect):

E
Now I'm a soldier,
C#m
a lonely soldier
A
away from home,
Am
through no wish of my own

Am does not belong to E major key, but it sounds very good. Is there a 'rule' for using out-of-key chords?

Thanks a lot......
