Bunny was born in Philadelphia, Pennsylvania on March 27, 1941. The industry gave him the nickname, “Mr. Emotion” after his heartfelt performances on stage.
After seeing Bunny perform at Atlantic City’s Ambassador Hotel, Independent Producers John Madara and Dave White signed him a deal that led to the release on Cameo of “Let The Good Times Roll” and “Feels So Good”. The groovy yet smooth tune reached 12 in the U.S. R&B Billboard charts, and his music career skyrocketed from there.
With the Philly soul sound so hot, Sigler got a chance to work with a number of acts as a writer and/or producer, including the Whispers, Ecstacy, Passion And Pain, Patti Labelle, The O-Jays, The Spinners, Lou Rawles and Carl Carlton. He cut tracks for artists on Curtis Mayfield's Curtom label, including Mayfield himself (Trippin' Out), and created a duet album with Barbara Mason. In 1976, Sigler set up an album deal for Instant Funk with Gamble and Huff's TSOP label.
