Before I put this one bed, can I just get some peace of mind regarding..
33a - Group from the East carrying around drinks (4)
I have the answer and the extra letter but, in all honesty, I can't say I'm 100% certain of the wordplay. For example, there's a word meaning 'group' that, minus the extra letter, leads to the answer, but it's anagammmed and there is no indicator - it does say from the East, suggesting it could be reversed - but it's not that either. You can also get to the answer by way of anagramming part of the clue but you then have to add another letter, only to then immediately remove it.
No doubt this is a lot simpler than I'm making it but, unfortunately, I'm so far down the rabbit hole now I'm having tea with the mad hatter!
