Yes, of course, Frank Sinatra has a special place in South Philly's heart. See, for example, the Sinatra karaoke contest slated for this year's 9th Street Italian Festival.
Lesser known is the special place that the sound of Philadelphia International Records also has in South Philly's heart. (There's room. It's a big heart.)
Having grown up to the musical stylings of Kenny Gamble and Leon Huff, neighborhood kids who shook their groove thing with WDAS disc jockey AJ Kemp at Holy Spirit C.Y.O. dances now invite the Sound of Philadelphia to their weddings, where Philly International artists like the Intruders and McFadden & Whitehead are in heavy rotation alongside Ol' Blue Eyes.
