Here is a new find, a collaboration by UK indie band "The Recovery Position" and Heather Nova.

The singer Ocean Reid writes about this song: the collaboration song 'Call' will be released as part of the forthcoming 'Recovery Position' album campaign. There are 2 versions. One version is myself and Heather as an acoustic track and the other is the full band and Heather.
