Sunday Times Christmas

[BIll]

Last two have stumped me for close on 20 minutes, so in the end I need help:
65a. About to be found back in pyjama cricket (5) C-R-A.
26d. Dry explosive in a letter from Athens (5) T-E-A

[Fair-Stumped]

65a circa - hidden backwards in clue

26D THETA?

[BIll]

Aha! Thank you

[BIll]

I actually have THETA written in but can't get the connection with dry explosive

65a circa (hidden and reversed)
26d t he t a

[factor-fiction]

You could have saved yourself 20 minutes by typing part of the clues into the AB search box as both have been answered before. Most questions are answered several times at weekends

[BIll]

Ah! Never even noticed that before

[magistra]

26d THETA
