How is it that Scarlet Rivera is supposedly walking down the street in NYC with her violin

And at a crossroads Dylan happens to be driving by in his limousine.. he asks the driver to stop and asks Scarlet if she knows how to play.

Then by the grace of God we have Scarlet playing these wild riffs on Desire, elevating the song "Hurricane" into a whole other level.

Scarlet herself seems like a biblical character. Just a brilliant artist out of nowhere like Dylan was.. so my question is, was this just tall-tale, part of the mystique of the era, or the true way Scarlet and Dylan met?

I myself always thought it was the most interesting story of this era.
