Dragonfly/Purple Dancer single

[macfan 57]

There was a Fleetwood Mac single from 1971 with Dragonfly and Purple Dancer as the B side. Does anyone know which lineup recorded this? Since it was released in March 1971, I'm assuming that Peter Green was not involved at all. Was this the Kiln House lineup plus Christine or was this the Future Games lineup with Bob? Also, I know that Dragonfly is on the 1971 Greatest Hits CD, but has Purple Dancer ever been released on CD? And, did Danny also write Purple Dancer?

By the way, it's nice to see this particular board come to life again.
