Bell Biv DeVoe made a return to live TV on Wednesday’s “Late Night with Jimmy Fallon,” performing two of their biggest hits with house band The Roots. Ricky Bell, Michael Bivins, and Ronnie DeVoe took it back to the ’90s with “Poison” and the web bonus “Do Me!” They received a warm welcome, as the crowd stood on its feet while they busted old school moves. Get back into the swing of things with BBD.
