Group Therapy: Rainbow Quiz

[Appletree]

Last minute panic. I'm going to send it in, regardless of whether I finish or not. I've been too busy to concentrate, and it's getting to the very last minute.
So, I've got down to single figures, and the last ones seem so simple, but I just can't solve them.
Can anyone give me some good clues for:
15: I left Sheila... (It MUST be an anagram of Shela, but I can't find one!)
19: Wild ducks wading...
26: She carried a satchel... (I know someone gave a clue for this, but I'm too thick to see it!)
37: Woman got the start of a flutter...
41: Well ordered characters...
42: Music for church service
57: After cigarette....
75: Extraordinarily bland rumours...
76: I've put HAREM but I don't really know why!
77: pretty pink flower of some sort. Wife thinks it's MAIDEN PINKS but I can't see the group in it.
78: Student group remains relaxed.

I'm sending it in anyway, with the usual cheque, but won't be able to sleep until I can see the answers.
I'm grateful for any assistance.
Many thanks

Thanks for the replies. The cheque is written and I'm putting a note that I'm only sending the answers in for fun - not for prizes, since I've had assistance.Looking forward to the next one now!

I wouldn't worry about having assitance, most people have assistance of some kind, whatever they say. Be it asking on here or looking on Google, or even just cribbing the answers given to other people on here. And you have only been given clues as to what to look for ,apart from 2 that I have given you. At the end of the day the main thing is that the charity benifite.

I agree with Jimjooles the charity benefits and we all get help thanks to this wonderful site. All I want is to see my entry getting 100 right not bothered about winning.
