70s female singers' acting showcase

Which turned in the best performance ?

• Olivia Newton John is this thread, OP.

• Bette Midler-The Rose

• I agree with r2.

• Diana Ross in Lady Sings The Blues

• Helen Reddy in Pete's Dragon.

  "It's a razzle dazzle day...."

• Well, truth be told, I shoulda won an Oscar for my groundbreaking performance in the movie "Slaves." I swear, those Hollywood folks just couldn't get enuf of that Barbra Streisand. Damn that hussy! Oh, don't have me control, alt, delete, and shut ALL this shit down!

• Miss Dionne, why didn't you do "Claudine"? That hussy Diahann Carroll snagged an Oscar nom for that role.

• Tina's Acid Queen was a lot of fun!
