I've set on the task of comparing the date/venue listings of the Gigography (http://www.new-order.net/no/gigs/, mirroring http://www.waterrat.com/nogig.htm) with what "the other site" (http://www.worldinmotion.net/neworder/gigography/1980.htm) has listed.
Here are the discrepencies I've found, for 1980-1. I'd kindly appreciate any corroboration, one way or another.
The NOOL site seems to be entirely deriviative of the Waterrat listing, at least for this time period in question.
1980
800904 WIM has "Brady's Liverpool", WR has "Warehouse Preston". If I recall correctly, the WIM listing is correct, as this was discussed a while ago, but I'm not certain.
WIM has 800920 for Maxwell's Hoboken NJ, WR 800921
WIM has 800926 Hurray's NYC, WR 800927
WIM has 800927 for _Tier 3_ NYC, WR 800928 for _Pier 3_ NYC
I wonder why these are all off a day.
1981
WR lists 810111 Rock Garden Middlesborough and 801105 Country Club Reseda CA which WIM does not
WIM has the Boys Club Bedford (21st) and Jenkinson's Bar Brighton gigs (22nd) in February, WR has them listed in March.
WIM has 810417 St. Andrews University, Scotland, while WR gives the date as 810416.
WIM lists the venue of 811121 Trenton, NJ as "City Gardens". I'm liable to accept this one.
