I believe Randy's health issues are on-going, and I don't believe he's sung in public in many years. As for Felder, as long as he continues to take pot-shots at the band through the media, they'd never be able to work with him. The guys don't need the stress and as for the fans, most of the shows announced so far are either sold out or very nearly so. The paying fans apparently don't care who won't be on the stage, but I agree, having all seven would be a great thing.
