My copy of "I Still Don't Know What I'm Doing" arrived today.
It includes another snippet of "Don't Dare (Love Is Hell)" - it's much lower quality than the snippet included on the main album, but presented in a similar way with the radio static at the start and end and seems to be cut from a verse rather than the chorus. Hopefully she releases it in full some time!
My favourite of the alternate versions are "Cold Places (Solo Version)", "I Don't Know What I'm Doing (Studio Band Version)" and "Fun (Solo Version)". The solo versions are just Nerina and piano for the most part except "Australia (Solo Version)" which is her with acoustic guitar.
