The dated rows on that venue page run through April 25, 2027, which is more than 30 days out and unused on other PR domains in this batch.
Local listings and the venue ticket page are the current dated sources for this replacement; the expired performer URL is the one that went blank.
The old link is the one that expired. Six The Musical is the unused venue with a last date of April 25, 2027.
The current list is at Six The Musical tickets.
