70's party games change PLEASE

Please please start adding some variety to the single artists you have in the 70's party games. It is ALWAYS either Neil Diamond, Chicago, Elton John, Fleetwood Mac, Bee Gees or Abba. 
There are so many other great artists from the 70's you can feature rather than these 5 time after time after time after time x100. How about Queen in the 70's for a start off !! A bit of variety each time PLEASE.
