Diana Ross turns 75-years old on Tues.–technically, she’s not a Baby Boomer, however, she’s an “Honorary Boomer” because she and her music are embedded in our shared generational memory.

Of all the girl groups in that era, The Supremes (Florence Ballard, Mary Wilson and Ross) really were rock n’ roll royalty: classy, always elegantly dressed and coiffed, they delivered a dozen #1 hits and 20 more that reached Top 10.

Ross was just as successful when she went solo, with numerous hits including her cover of “Ain’t No Mountain High,” “Touch Me In The Morning,” and “Endless Love,” her #1 duet with Lionel Richie.

In 1964, “Where Did Our Love Go” became The Supremes first #1.
