Formula to reverse two sets of names in same cell

Hi

I wonder if someone could assist with a formula to reverse two sets of names in a cell please.
Scenario
I have been sent a large set of data where the names are like this

Smith Fred - Hunt George

I would like to change it to

Fred Smith/George Hunt

I've used =MID(A1&" "&A1,FIND(" ",A1)+1,LEN(A1)) before to reverse two names, but this goes beyond.

I'm not too worried about anomalies that might occur, I can manually edit them (where a middle name is introduced or a Jr or Sr is added)

Thanks for your thoughts
Neil

Using "helper" columns with initial data in A1

in B1 =TRIM(MID(A1,1,FIND("-",A1)-2))

in C1 =TRIM(MID(A1,FIND("- ",A1)+2,255))

in D1 =MID(B1&" "&B1,FIND(" ",B1)+1,LEN(B1)) & "/" & MID(C1&" "&C1,FIND(" ",C1)+1,LEN(C1))

Hope this helps.

Thanks both, I like both approaches and will test later to see which is easiest to implement.
