“There’s been a few emails exchanged and a few jokes about how we’ll get our hair that big and long again, he told Billboard.com. “We might all have to go in for weaves. If we got together and wrote a couple of songs and put out a single, that’d be more important to me than playing a show; just getting in a room together.
