When Coolio took the stage at Black Bear during the 'I Love The 90's Tour' he gave a shout out to the purple one, Prince and the great Muhammad Ali. 

The 'Purple Rain' cover was short with the lights going purple and the iconic Prince symbol on the screen, but I enjoyed it. I wasn't expecting Coolio to also give a shout out to Ali too, but apparently he felt compelled to do it. Overall I enjoyed the show, but I think the highlight of it was Salt n Pepa's performance.

Check out Coolio's tribute in the video below and let me know what you thought of the show in the comments.
