I went down a rabbit hole of people showing people how to play the opening of Bridge Over Troubled Water. Very amazing. The guy who actually did it was Larry Knechtel who was part of that team of session players in Los Angeles that played all the Beach Boys album and The Monkees and the Mamas and the Papas. I love the YouTube universe. Funny how once upon a time it was about bootlegs and now it’s like Star Trek ‘computer, Earl Grey.’
