Reckon tours about to happen - very soon? (7)
I believe the answer is:
tonight
'very soon?' is the definition.
'reckon tours about to' is the wordplay.
'reckon tours' becomes 'night' (I can't justify this - if you can you should believe this answer much more).
'about' says to put letters next to each other.
'night' after 'to' is 'TONIGHT'.
'happen' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tonight that I've seen before include "West Side Story number" , "Later today" , "after supper?" , "Late today" , "The end of today" .)
