"Of course, the wind sort of swept up and the music was flying around in mid air and they were trying to play off it. You had to be there. It was quite funny"

This quote by Roy Wood paints a vivid photo of an amusing and slightly chaotic scene including musicians battling the whims of nature. The imagery recommends an outdoor efficiency where the wind disrupts both the sheet music and maybe even the instruments themselves. The phrase "the wind sort of swept up" conveys an unexpected rise in wind, which adds a component of surprise and spontaneity to the moment.

Wood's use of the phrase "the music was flying around in mid air" can be analyzed in a couple of ways. Literally, it could imply that the sheet music was physically raised into the air by the gusts of wind. Symbolically, it recommends a moment of disarray where the music, meant to be a structured and controlled art kind, becomes scattered and unrestrained, much like the leaves in the wind. The reality that the artists were "attempting to play off it" highlights their professionalism and flexibility in responding to the scenario, albeit humorously.

The statement "You needed to exist" implies that the true essence of the scene-- the mixture of aggravation, amusement, and possibly even sociability among the artists and audience-- can not be fully caught through words alone. The humor arises from the unexpected scenario and the image of musicians valiantly trying to preserve their efficiency in the middle of the turmoil. It beckons to the idea that certain minutes bring a special appeal and hilarity that are best appreciated in person, with the full sensory experience of sight, noise, and shared laughter.

Overall, Roy Wood's words encapsulate the unpredictability of live efficiency and the whimsical moments it can produce, advising the audience that sometimes, the most unforgettable experiences are those that divert off script.
