"There is still this R&B album I want to do," Stewart, who kicks off his North American tour in July, told Reuters.
But, added, Stewart, his record label J Records, isn’t too keen on a country album. "There's a Country and Western album I'd love to do, although the record company doesn't want it," he said. "We are still in the throes of talking about it. I very much doubt whether we will get it done this year."
Regardless of the genre, Stewart says he wants to continue performing until he's 70. "I do love it," he said. "I actually enjoy this job that I do. I probably would miss it."
