Not Lindsay Wagner -- older, and not American. Known internationally.
Started acting as a child, then became known more for her singing, although she continued to star/appear in some big movies after attaining stardom in the music field. She has worked with Sir Alec Guinness, Peter Ustinov, and Fred Astaire.
Is listed in VH1's 100 Greatest Women of Rock N Roll, (but you can actually understand the lyrics when she sings) and has sold more than 70 MILLION records (worldwide). She won two Grammys (USA), had at least 15 Top 40 hits in the USA, and over 150 Top 40 hits worldwide. Is still performing concerts, including benefits for UNICEF and other charities.
Had her own TV show in her country, and was once named "Outstanding Woman television personality of the Year", but has only had a few specials (as far as I can tell) in the last 20 years.
I didn't intend to give so much info, but until I started reading her biography, I really didn't know the extent of her versatility, the length and success of her career in music and acting -- I've known about her for many years, enjoyed her singing, and admired her personally for some actions she has taken during her life, but didn't know the rest. I figure most players here won't recognize all the tips, but some will recognize her from something I said.
