Is Diana Ross becoming the most successful & longest running Motown live act ever?
With new tour dates announced, I'm wondering if Ms. Ross could be considered the most successful live act ever. Michael Jackson toured to much larger crowds, but less frequently; the Tops/Temps is/are on another go-round but most members are not original members so to my evaluation don't count. Gladys Knight could be on the list; of course Stevie still commands arenas but also in frequently. So, based on an imaginary formula of number of years / number of headine concerts / number of seats sold, would Diana hold the record?
