Can you name the first time you saw a Motown Artist [or Former Motown Artist] Live In Concert?

My first was The Spinners at The Apollo Theater, NYC, January 1973. It was a double bill with The O'Jays. The Spinners were ex-Motown at that time and just started their Classic Run of hits with Atlantic Records so it was a double shot of Philly Soul [and a Great Show].

From there I go to 1982 and a show at the Palladium, NYC for a show featuring Martha Reeves [no Vandellas], Mary Wells, Jr. Walker & Ben E. King. I remember that Mary & Martha had to play with a 'pickup up band' that didn't know the songs very well so it was less than perfect.
