Jonathan Schwartz (born in New York City in 1938) is an American radio personality, known for his devotion to traditional pop music.
Schwartz (the son of songwriter Arthur Schwartz) worked at New York's WNEW-FM from 1967 to 1976, followed by stints at WNEW-AM, WQEW, and (currently) WNYC. Schwartz also served as programming director for XM's now-defunct High Standards channel, and continues to host a daily show (also called "High Standards") on Siriusly Sinatra.
Schwartz is best known for his two four-hour-long weekend broadcasts, dubbed the Saturday Show and the Sunday Show, which offer an eclectic mix of music along with conversation and interviews simulcast on WNYC and the Siriusly Sinatra channel on Sirius XM Radio. (Due to contractual obligations his Sunday broadcasts are not available on WNYC's web audio stream.)
