With all the Whitney Houston tributes in the past week, one from a 90-year-old grandmother from Utah stands out.   With help from her grandson and caretaker, Adam Forgie,  Jeanne Harr - who  is legally blind  and has moderate  hearing loss - posted a video of herself dancing to Houston’s "I Wanna Dance With Somebody” that has now gone viral."’I’m doing this in honor of the late Whitney Houston. It’s very hard to think of her being gone,”  says  Harr at the start of her tribute.Harr’s  grandson says on his Facebook  page that  "one of the few things that makes her happy is dancing.”  This isn’t her first dance video. Harr is a regular dancing machine.  Check out some of her other work  here.
