Along with Robyn Hitchcock, composer Zafer Tawil and a number of others, TV on the Radio's Tunde Adebimpe has recorded a song for the soundtrack to Rachel Getting Married.  And for his contribution Adebimpe quietly covered Neil Young's "Unknown Legend," a track from the icon's 1992 Harvest Moon.  The near a capella cover comes in great contrast to the variety of tracks Adebimpe recently released with TV on the Radio on the critically acclaimed Dear Science.  The film itself, which also stars Adebimpe alongside Anne Hathaway, is set for a theatrical release of December 5.
