Everyman 3829
I'm stuck on ones everybody else must have got:
11d Wild youth ate nuts hastily - -i-h---/d---y I think it's an anagram but of what?
And: 23a Comedians heartless joke describes higher echelons -o-n/-----e

[elliemay1]

without delay

[Lie-in King]

11d Without delay - anag (nuts) 'wild youth ate'
23a John Cleese - 'j(ok)e' (heartless, round) anag 'echelons'

[Toorak]

Without delay - anagram
John Cleese j(ok)e around anagram of echelons

[scorpiojo]

Without delay anag
J ohn Cleese (anag echelons)inside j(ok)e

Many thanks!
