 The familiar theme song of the original, "Park Avenue Beat," was replaced by a generic dramatic fanfare.While several production personnel had worked on the original "Perry Mason" series (including executive producer Cornwell Jackson, producers Ernie Frankel and Art Seid, and director Arthur Marks), the series was made without the participation of any members of the original cast, with Monte Markham taking over the role that Raymond Burr played in the original series.Produced by 20th Century Fox Television, it aired Sundays at 7
