Paul McCartney poses with Philadelphia police

SOUTH PHILADELPHIA (WPVI) -- The Philadelphia Police Department got two thumbs up from a very special guest in South Philadelphia Tuesday night.

Legendary musician Sir Paul McCartney posed for a picture with a few of Philadelphia's finest while in town for his One on One Tour at Citizens Bank Park.

"Whenever Sir Paul is in town for a concert, he always has a kind word for our officers! Does the PPD have 5th Beatle status?! Maybe!!" the PPD wrote on their Facebook page.

The image was a good recruiting tool in the eyes of Lieutenant Stephen Clark.

"Stop a crime, save a life, get two thumbs up from a rock star knight. Join @PhillyPolice at http://joinphillypd.com," Clark tweeted.
