Famed Houston real estate developer Welcome Wilson celebrated his 90th birthday in style — that is, with 500 of his closest pals! One of the first events hosted at the new Post Oak Hotel, his bash was attended by beloved politicians and fellow philanthropists, who made donations in Wilson’s name to UH’s Jack J. Valenti School of Communications. And culture vultures hit the Hobby Center for an exclusive, intimate performance by the O’Jays. The show, put on by Music with Friends, was bookended by Champagne-savvy receptions.
