Joe, old guys like me know who the Buffalo Springfield are. The only problem is that the name is trademarked by Neil Young, Stephen Stills, and others.
They may not like you using their name, or trying to sell this domain.
Your only bet would be to seek permission from them to establish this as a "fan site" for the Buffalo Springfield. It then may be worth something decent.
Of course, you could try to use name for another field other than music and recording, but I don't know what that could be. :imho:
