I always liked Mathis. And when we were still back in Portland (pre-Louie Louie), grinding out those 2 and 3 hour gigs, we needed to give the dancers a break from time to time.
One day, as I was setting up the band (I doubled as roadie in those early years), I was testing the mics and happened to break into Chances Are. The enhanced echo built into the armory we were playing that night sounded a lot like the famous echo chambers at CBS to my young ears. The overall effect was pretty good.
There were a few kids who had come early, and when I finished, they all clapped at my a Capella effort. Revere looked at me kinda strangely, being more used to hearing hard rock and roll issue from my mouth, and said, "You sound pretty good on that, Markus."
So we added it to our repertoire.
And here it is again, 50-odd years later, along with some of my other favorites. Hope you enjoy them.
