Garden State Publications #4785709. Published by Garden State Publications (A0.934984). From the 1974 album Streetlife Serenade, Root Beer Rag is an upbeat and rollicking instrumental that came at a time when ragtime music saw an uptick in popularity upon the success of the movie The Sting.  Although not written in a traditional ragtime form, this duo version of the Billy Joel tune tries to capture the same spirit of the original and places the melody and accompaniment in both the vibraphone and marimba parts.
