So after reading a bit about each member I've decided to give them new signs!
Keith is now a Libra: They are the sign of love any kind and they crave it but are always ending up with less than they need, can be very reclusive when deeply depressed and when shown any kind of affection they cling to it like a lifeline when it is severed they become very emotional or self loathing.
John is now a Leo: They are alluring without trying, are obsessed with looks like a Peacock but have a loving nature and are protective as fuck, Don't fuck with a Leo.
Pete is now an Aquarius: They are intelligent a bit detatched, very gung ho to get things done and have a wild imagination to boot, they are the Dreamers.
Roger is now an Aries: They're scrappers though are known to have a soft side but can be downright ruthless when angry or provoked.
