Rob - I doubt streetlights have anything to do with it - I frequently hear diurnal passerines out in the dark middle of nowhere while doing Nightjar Survey routes. I had a couple that I couldn't ID last Thursday - one may have been an Indigo Bunting. They're often an abbreviated or garbled version of the regular songs, so I can't always positively ID them to species (with the exception of "regular" night singers like Sedge Wrens and Henslow's Sparrows.)
