Have got 7 of the 8 themed answers but am struggling with bottom half as follows:
24a "Order: eyes left? right? whichever way you like?" (9).  I've got  F - E - - - E - -  
 I'm assuming the answer is FREEWHEEL but that then leaves me struggling with 25d "Offspring's letters returned" (4)     W - E - 
and 22d "Understand revolutionary interrupting revolutionary" (6)  C - L - S -
Also, despite earlier post still don't get 27d "unspecified ordinal number restricted by obsolete letter" (4)  E - T - 
Hoping someone can help put me out of my misery
