Growing up in Dayton, OH, I saw the McCoys at a teen club in a basement level of a shopping center.
They were the opening act on a 12” high stage and then stayed on stage to be the backing band for Simon & Garfunkle’s “Homeward Bound” tour.
He played on Steely Dan tracks - “Show Biz Kids”, “Chain Lightening” and Donald Fagen’s “Nightfly” album among others.
If you’re a Steely Dan session man, you are top notch. Fagen and Becker only selected the best. There’s a good SD documentary out there, IIRC about the making of Aja, and their perfectionism just shined through.
