Fawn Hall, who made her television debut testifying about former boss Oliver North before a Senate committee, will be co-host of a network special its producers hope is an upscale version of "The Lifestyles of the Rich and Famous."

Miss Hall was chosen "because she is very spontaneous and has a presence that is indicative she can handle this kind of assignment with zest and energy," Gary Pudney, an ABC television vice president for specials, said Friday.

"M-W Men and Women," based upon M and W magazines, will air the first week in June. Pudney said it is to combine "Entertainment Tonight," "60 Minutes" and an upscale version of the show that displays the opulent lifestyles of the wealthy.
