Amazing Grace can also be performed to the tune from the theme song to Gilligan's Island. I do not recommend it, because for years after you figure this one out you will not be able to sing Amazing Grace to any tune BUT the theme song to Gilligan's Island.
Most worship songs are repetitive, almost chantlike in their structure. Even if the chords are difficult to learn once, they will be used over and over and over again in other songs. For more simply structured songs, I recommend looking to the old standards and country gospel.
Will the Circle Be Unbroken
Peace Like a River
Shall We Gather By the River
Etc., and so forth.
Granted B chord amnesty by King of the Mutants (Long live the king).
