Help appreciated with the wordplay for these.....
30a One maybe getting tight in grassy area around Herts town (10) - DRAWSTRING
I know Tring is in Herts, but that leaves 'Draws' for 'Grassy area' - which I don't get - (the closest I came was 'A small gully').
50a Be a busybody, emulating a smug Jack to maximum extent? (4,1,6,2,5,3) - HAVE A FINGER IN EVERY PIE
I get the definition but that's about it.
34d Educational subjects are out of date, embraced by old-style politicians (7,4) - LIBERAL ARTS
i think the 'Old-style politicians' could be LIBS, but I'm not even sure about that.
