Grandmas dancing to today’s top music hits has been popular, we featured a grandmother dancing to Tyga’s ‘Rack City’ earlier this week. Adam Forgie’s 90-year-old grandmother is not afraid to bust a move to LMFAO’s ‘Party Rock Anthem’. To make this video more amazing she is legally blind diagnosed with Severe Macular Degeneration, has very little hearing and this is her first time listening to the song.
