Too whiney sounding for me. Definitely not the “blue-eyed soul” type of singer or vocalist, like a Leon Russell or Edgar Winter.
My “Three Dog Night” would be Mickey Thomas (Starship), Perry, and Steve Walsh (Kansas) with Glenn Hughes (Deep Purple) on Bass, Mark Stein (Vanilla Fudge) keyboards, Johnny Winter on guitar, and Don Henley on drums-—none of these are necessarily the greatest player on their instrument, but this is if I was putting a band together where everyone was a killer singer.
