LED ZEPPELIN:
NAH, LEAVE IT...

Robert Plant recording "Black Country Woman" with the Stones Mobile at Stargroves (Mick Jagger's house), England 1972.

"During the recording of "Black Country Woman", Robert sang his lead vocal outside so that we could get the effect of no acoustical interference. However just as he was about to sing, an airplane droned overhead. On the final mix both my comment, 'Er, what about that Airplane then…?' and his terse reply 'Nah, leave it …' are preserved for posterity on the album."
