Eighty-seven year old Pat Sellers, laid off from the Philadelphia Cricket Club three years ago, has started doing what she has seen young people doing to try to make ends meet. Since July she has been busking on the street.  She serenades passersby on her electric keyboard with show tunes and old time favorites outside Kilian Hardware, with electricity provided by the store,  in the hope they will put money in her donation bag. On a recent Sunday, the musician, striking in her poofy, coifed silver hair and smart blue and white pants outfit, tapped out songs from Les Mis and Nat King Cole. Watch video and interview here.
