SF's possibly on a Tarantino kick with that suggestion of 'Don't Let Me Be Misunderstood', which a number of artists has covered - Santa Maria's extended one's is going to be most memberable to recent moviebuffs. However I don't think any version of it would have a "trust me, I'm harmless - really!" effect and am at a loss to recommend one for it.
