This time

 Michele 

invited Ned Roberts 

Benjamin Folke Thomas 

and Catherine Williams to come round and play.

Amongst the acts

that Michele Stodart (yes, this time without her brother) presented this time were the sisters

Kate

and Nina (or was it the other way round?)

In some of their songs they reminded me a bit of Alicia Edelweiss (maybe not in the delivery of the song, but in the way the songs seem to be created)
