Iggy Pop and Yoko Ono have teamed up on record to benefit a Miami, Florida animal rescue organisation.

The pair hit the stage together as part of an Ono tribute gig in Los Angeles in 2010 and performed her track Waiting For the D Train, and now the two friends have recorded the tune for a limited-edition single release, which will also include Iggy Pop's cover of Ono's I'm Going Away Smiling.

The two tracks will be available digitally on 13 September (13) and all proceeds will benefit Paws 4 You Rescue of Miami.
