Jerry Lee Lewis - Live At The Star-Club, Hamburg Germany/ April 5,1964 is one of the best live concerts ever. The Nashville Teens of "Tobacco Road" fame were JLL's backing band that night. It's definitely in my Top 5.
@TheDarkSide73: You seem to be a little obsessed with the 13 year old cousin..;-) But I agree totally: Elvis & Jerry Lee are Rock'n'Roll, as its best. Some others are, too. But Jerry Lee is the killer, and when I saw him live in 1981 he really deserved to be called that.
