Drums: Joey Waronker
He's one of my favourite drummers, and not just because he played on our record. I love everything he's ever done. He's a bit of a legend. I've actually only ever seen him play in a studio setting so I'd love to see what he did on stage.
Bass: Mike Elizondo
We've worked with him in the past. He's also worked with Dr Dre, Fiona Apple and Regina Spektor. He's a fabulous musician and a fabulous bassist.
Keyboard/piano: Helen Marnie and Mira Aroyo
I want the two girls from Ladytron. I absolutely love them. In terms of aesthetic, Tegan and I don't have lots in common with Ladytron but I always thought they were the coolest band.
Vocals: Ryan Adams
My earliest memories of touring were with him in the early 2000s. I remember being incredibly envious but also so admiring of his talent. He could go out onstage solo, with just an acoustic or electric guitar, and play a four-minute song and have everybody in the palm of his hand.
Backing vocals: Patsy Cline
I love girl/boy vocals. Am I allowed to bring Patsy Cline back from the dead? She's one of my favourite female vocalists ever. I guess it's indicative of where I am in my life right now that I haven't even thought about adding a guitarist! Do people still have those?
