Yes Emmanuel lewis was a brilliant actor & yes I also wonder if he can still do those movies, like in Chicago, & its a shame that Webster didn't carry on & we see grow up to an adult in the show, what does Emmanuel think?
Sadly No, he recently sang at an awards show in 2019, he was in a wheelchair. he was singing For Good from Wicked. While you can hear the singer he used to be, time has not been good to his vocal cords. you can find it on youtube.
Strangely enough, Ben Vereen played Webster's Uncle Philip, James Avery played Will Smith's Uncle Philip, but Ben Vereen played Will Smith's father Lou who was not as close to Will as Uncle Philip was to Webster.
