And for anybody keeping score, after KFBK-A/SACRAMENTO host TOM SULLIVAN served as RUSH's initial fill-in, KOGO-A/SAN DIEGO's ROGER HEDGECOCK, like SULLIVAN a frequent RUSH fill-in, took his place behind the "golden EIB mic" on WEDNESDAY. Regular RUSH surrogate WALTER WILLIAMS will do FRIDAY's edition, and WISN-A/MILWAUKEE's MARK BELLING is on tap to fill in for early next week, followed by "FOX NEWS SUNDAY"'s TONY SNOW on WEDNESDAY and THURSDAY and MATT DRUDGHE on FRIDAY.And contrary to rumor here earlier, Joan Rivers will only be on in Providence........Talk WBAL-A/BALTIMORE does an about-face and will resume carrying the RUSH LIMBAUGH fill-in show...
