Since we're guaranteed a classic set today, maybe another one of these will help pass the time.
When sorted alphabetically by artist and then song title, there is only one instance (out of over 12,000 entries) where 2 artists have appeared consecutively with versions of the same song*. Name the one song & two artists.
*This means that the first artist has no songs after the one in question, and the second artist has none in front. Which is a roundabout way of pointing out that they are either obscure only-in-the-Bay-Area bands or OHW's.
