I was at her Lowry concert on Wednesday night and commented the same in the Double Bass lounge. He's German and played it straight, sideways like a guitar, picking chords, and with a bow. She also played piano and guitar, had a sax, dbass and drums too and it was one hot band: the cello and double bass interplay was exciting and innovative. She was way more Jazzy than her albums, which I loved.
Melody said she'd "stolen him from Germany", not sure if he's done all the European date or not.
