Shenandoah – http://www.youtube.com/watch?v=X17XzZLD3JQ (Wait through the Japanese intro till they sing (beautifully)!)

Long time ago – http://www.youtube.com/watch?v=hpzO858rCNA

Sure on this shining night – http://www.youtube.com/watch?v=28ax1Pgh9S4 (a lovely recording and performance)

Medley from Guys & Dolls – http://www.youtube.com/watch?v=IIANxBKRb18 (amazing energy from these kids – look out for the Tinhorns Fugue!)

My Evaline & Sister Mary – Richard Ashworth is preparing MP3 versions of these

Alexander’s Ragtime band – http://www.youtube.com/watch?v=B41Ol3s5vp0 (OK this is an all women choir but they sing all the notes – in the middle “bad op bop ba” section they go through with just the top line and then again adding the second line and finally all three lines)

Blue Moon – http://www.youtube.com/watch?v=TT2H-9MU94Y (at night on the River Cam) [n/a]

Summertime – http://www.youtube.com/watch?v=BKdgiXuj_Zk (a bit raw but the notes are there)

I got rhythm – http://www.youtube.com/watch?v=D-eRl6k0zRQ (don’t be deceived by the slow first bars)

Lets do it – http://www.youtube.com/watch?v=iHAAE4qYdMc (couldn’t resist this incredibly winning Manila college canteen performance over an amazing German a cappella group and a strange French performance in an echo chamber)

Ain’t misbehaving – http://www.youtube.com/watch?v=7_npP9rJJlc

West Side Story – http://www.youtube.com/watch?v=q16L08uUBS8

So far I can’t help with …
