This is a slow groove in Am. Nice, memorable melody to it, fun to play. The mandolin (JR?) floats on it, then states the melody at the end. He takes it out with an Am arpeggio, then strums a chord to end it, which sounds to me like a m6. Does anyone know the voicing used? Also, what does E.B.A. stand for? Thanks.

P.S. reading Still Inside, quite fascinating.
