As it's a numerical puzzle this week, the usual wording doesn't really apply.
Help with the clues is available here, as is help with the theme. The help should be of a gentle nature - enough to assist, not so much that it spoils the puzzle for others.
There are many regulars on these Listener threads, but newcomers are always welcome.
The Listener is a unique puzzle and should be treated with respect.
PS An early post as I'm going out soon and might not be back for the usual 4 pm start!
