I have very fond memories of travelling to visit a young man I met thru my cousin. We were going to a university dance & we listened to a Linda Rondstadt album practically on repeat!!!!! Like you my brother loved her & loved the Rolling Stone cover of her in lingerie. Those are some great memories. She has, hands down, one of the greatest voices ever. Real talent, no machines needed.
As a very young fellow, I saw her front for Steppenwolf. (It might have been with the Stone Poneys). She was barefoot in a very short dress, obviously without underwear! And talented too!
