Thanks to both of you.... I'm getting closer ...working it out on 12-string and mandolin... I'm not sue what the tuning or instruments all are on the recording I have ... but maybe I'll post once I get the base line worked out ... it does seem to fit roguly with these chords when I sing it I'll check it out with the recording it seems like many of the chords are variations with added 4ths 2nd etc...

Thanks again for the help
