Stuck on last two
30a "Fellow's excited cry when taking the plunge" (5)
I?I?O could it be IAIDO (relating to Japanese swordmanship) ?
I can see I DO fro taking the plunge but where does the cry come in?
57a "Very good mark, mostly, for wine supplier? (5)
P?N?T Looks like PINOT for wine but don't get the very good mark
Any help much appreciated
