In the In the mood for a melody video, Robert Plant squeezes a lemon, referring to a line in the "lemon song" "squeeze my lemon till the juice runs down my leg"..In another scene a bright sunlight awakens a child..a possible reference to another zep song..the line "children of the sun begin to awake". Pretty interesting as this was a time when Robert Plant was publically not interested in exploiting his Zeppelin past...
