Blackthorn Tree - Weird growth

Oh dear ... my usual home grown sloe gin making is looking highly unlikely for this autumn, as my blackthorn tree is developing strange characteristics - odd shaped fruits and weird stem development. Could anyone enlighten me to the cause, please? Thanks in advance! (Sorry, can't find a way of rotating the pictures to portrait!).

Taphrina pruni, a fungus, creates Galls where there should be Sloes. No stone, they're empty and known as Pocket Plums

Thanks, Nut Cutlet. My damson tree has these 'pocket plums' too.
As for the blackthorn stem growth (Picture 3) - I've never seen this before. It's like a contorted drying out celery stick - and slightly creepy!!

Maybe something else is happening with the stems.
