What made you keen to be involved in this show?
Harwood: Because these incredible songs should be heard, and live is best - there's magic in them thar trills (plus I bloody love these women).
Laing: Would not miss an opportunity to work with these wonderful women, not to mention the band.
Will there be any new songs in the mix?
H: I do a couple of newish originals but there are so many songs like Maxine, Kennedy, Escaping, See What Love Can Do, Asian Paradise - the setlist is already heaving with gems.
L: I'm going to do a couple of songs that weren't included in 2009, but they're not new per se.
Which song by one of the others would you most like to sing?
H: Thankfully Shona lets me rip into Soviet Snow with her, which is a vocal force majeure.
O'Neill: Soviet Snow for me too - it's bigger than a snowman's breakfast.
And which song do you wish you'd written?
H: Danced in the Fire by Sharon - I've written songs about agonising break-ups, but this one takes you right into the middle of the raging river.
L: For me it's See What Love Can Do by Annie Crummer and the Herbs.
Seeing as you'll be performing at the zoo - which zoo animal would you be and why?
H: I'd say I'm more cockatoo - I'm annoyingly optimistic.
L: An elephant, we never forget.
O: Any kind of cat!
