Stephen Stills wrote 'Find The Cost of Freedom' after visiting a Civil War battle site and the emotion is still potent today: 'All the brave soldiers that cannot get older been asking after you ... Find the cost of freedom buried in the ground.' The a cappella texture makes it especially moving. 'Come Go With Me' - Put a special soloist out front with this doo-wop hit of the '50s! Here's a super arrangement of the top pop hit 'Stand By Me' from 1961. 'Sixteen Tons' - Here's a great a cappella setting of the Tennessee Ernie Ford work song from the '50s. Excellent independence of voices!
