They should launch a “Bucks Fizz” edition
Or better still, a "Sugarbabes" edition. Similar story: over time, each of the original 3 members left and was replaced. Then in 2012, the three original girls formed a new trio, "Mutya Keisha Siobhán". A slightly better outcome though, as they were eventually able to reclaim the Sugerbabes name.
Branding is everything. The battle between BMW and VW over the Rolls-Royce name is one of the more fascinating stories in automobile history.
I love a rathole.
