Pink is extremely talented, and really can sing, unlike so many singers around nowadays. (They all sound like uluvating goats to me, frankly).
To sing while upside down is extremely difficult. As a singer myself, I recognize her abilities.
However, I will debate that talent necessarily goes with class. I’m sure she has some virtues. But I saw an interview once with her, when she basically admitted the name “pink” came from what a black man said when she lifted up her skirt and showed him her private area.
This does not equate with “class” for me.
Really? Yikes. And I just recently read somewhere that she got her stage name from a nickname her friends gave her and it was because she used to blush a lot.
