It's odd, admission means to acknowledge something - which Linda Ronstadt did recently. Admitting that she has Parkinson's and can no longer sing. It's got to be a hard thing to admit, you can no longer do what you have committed your life to.
.
Admission also means to be invited into a school or club or group. And with this song - just Linda and a piano - i admit you into my club so you understand how much I loved her in my youth.
