You probably intended for players to make their guesses from personal knowledge, rather than a search of teh Interwebs, right (I checked, and it was trivially easy to get the answer)? If so, you may need to find an easier lyric, given over 100 views and no guesses so far!
Hm…not playing at the moment, but need answer fast. A co-worker just threw out the lyric ‘Venture a guess, in the sunshine’ expecting I could ‘get it’, but I have no idea.
