The first node, the Anchored Inn, is correct and current.
The second node, the punk club Acheron, is no longer a music venue, but is now operated as a club by The Anchored Inn, according to search results.
It is unclear to me which name is presently in use, if the node has been renamed as Anchored Inn, or if it still retains the old name as The Acheron -- a local would have to clarify.
Both nodes have the same address (57) but are two different spaces.
The second node is probably amenity=bar now.
This is not deduced from the Note maps.me content, but from several 2016 news articles unearthed via a text search, which as such should be treated with suspicion, and local observation (name, function) given priority.
