Hi Dutchy and Buzz boy,
For 37D. I also have 'medal'
decoration = medal
left = L
L + the letters of 'made' = medal
For 69A. I also have 'bankmanager'
*71D. rescue vessel = ark
D= 500 (in roman numerals)
went off = take off 500 from the word dark to give 'ark'
*74A. crackers = skyrockets
they will reach great heights = skyrockets
Hope this helps!
Regards, Butterfly
