That brings both the weekend Open House Party and PM drive/weeknight “Party Playhouse” programming to Westwood One. The big syndicator says the two shows are clearing in 30+ markets on more than 75 stations. “Open House Party” with John Garabedian began on Boston’s “Kiss 108” WXKS-FM in 1987, and its recent live guests have included Lady Gaga, Jay Z, Miley Cyrus, Akon and Shakira. The Saturday night “OHP” is still anchored by Garabedian. The Sunday night edition is hosted by “Wired 96.5”/WRDW Philadelphia personality Kannon. Westwood Network Division President Gary Schonfeld says the company “continues to expand the breadth and depth of our programming roster.”
