To celebrate Elvis Presley?s 75th birthday on Friday, members of the Marion Senior Center invited their own Elvis (Marc Baker of Wichita) to sing The King?s rock ?n? roll hits from the 1950s. Baker, a deputy sheriff with Sedgwick County by day, said he enjoys impersonating Elvis in his spare time. It?s the fourth year Baker has been invited to sing and dance at the Marion Senior Center. Although the crowd was smaller this year due to the weather, his performance was still a hit. Baker said he impersonates Elvis throughout Kansas and across the country.
