This was never a Ritchie Valens song. "Stu" is Ian Stewart of the Rolling Stones as mnkyonastick indicated. When Zep started recording in about '70 in the Rolling Stones' Mobile studio, Stu just started playing an out of tune piano and they all started jamming and came up with this. The Boogie-Woogie style of playing paino was Stu's forte. Obviously this was a leftover recording they would later release on 1975's "Physical Grafitti."
