Maria Bethania, who’s on a mini-tour with only songs by Chico Buarque through five Brazilian cities, is planning to do another major project involving the singer and composer from Rio. Glamurama found out that the diva is thinking of recording Chico’s songbook. The endeavor doesn’t have a set date yet. "It’s a project for the future, Maria doesn’t even know if she’ll really do it. They are only studies and a project she has in mind," said the singer’s rep. Currently she’s focusing on the launch of a CD of new material in 2012.
