Update!!
I've been bashing through the book for a few days now, and I've now decided what I am going to concentrate on.
List A: A:1 - Sarabanda: Out of the 3 A pieces this is the one I like most, apart from being unsure on how to trill. I liked the Mozart, but it didn't grip me that much, and hopefully I could play the Corelli better. The Hassler just confused me.
List B: B:3 - Banges Herzelein: When I first played this I thought "I'm definitely not picking that" but then decided that the second half was really pretty and in fact I really liked it. It conveys such emotion to me, in the second harp, there seems to be a feeling of hope which then gets dashed by the end. I did really like the Andante also, but I really love the Banges at the moment
List C: Mini Rag - hopefully! I like this one the best. Not sure I'll be able to play it at the c. 144 it says as 'suitable' at the bottom. The Old Cuckoo Clock, I knew that I'd get lost with the quavers in the right hand, I'd end up miscounting or something. Moebius was a bit wishy washy for me..

Better do some proper practice soon, including scales! Luckily I have the scale book and sight reading book from when my brother did grade 1.
