Please explain these to me.
Gutless junkie with pointed instrument. Ans Jews harp. I get the sharp bit but how does gutless junkie =jew?
A short revolution finally ending in state today. Ans Saturday (it may be that the crossword appeared on a Saturday) . I thought it might be Say (state) surrounding a tur(n)but where would the d come from?
Maybe another one being broadcast. Ans on the air =being broadcast but why "maybe another one"?
What one may be called after standing a drink out East . Ans Namesake. It's an across clue and I get both name and sake but can't see how you get namesake and the significance of standing.
Twig from plant producing fibre? Quite likely. Ans Cotton on = twig but how does on come from quite likely?
Thanks

gutless means removing the middle letters

[bookbinder]

Gutless junkie means remove the 'innards' of 'junkie', and you get j - e, then you add 'w' from 'with' to get jew's harp.

3. on the air is an anagram of another, plus I = one.
