"When they call out 'I need Sergeant Jason Rothermund up here' over the mic in front of thousands of people, you kinda have to go," said Rothermund in Facebook post on the Lexington Police Department's page.
He continued, "I heard the guy who was playing guitar ask over the microphone if I was in the park… he was inviting me to come up to the mic with him. My guys set me up! After saying I was a police officer, the crowd urged me up there. So I kinda had to go."

According to Lexington's WKYT, Rothermund is also the Fraternal Order of Police Bluegrass Lodge #4 president and wrote in the post he loves '80s music. So, naturally, he stepped up to the occasion and performed a soulful cover of the Bret Michaels-penned hit -- to which Michaels responded with praise.
