My husband and I are both Sintra fans, and were long before we met.
When we began to share our CDs with each other, it became apparent that we were, actually, fans of two different singers.
He prefers the world-weary, old gambler looking back on life, the mid-life Frank.
I prefer Frankie: the skinny band singer, whose voice makes me swoon.
Now, you can see the difference for yourself. The same song, sung by my young Frankie (first) and then by my husband's world-weary Frank.
