Interesting. Thanks Paul!
The gig I referred to (above) was reviewed in Sounds
by Chas de Whalley on 20 November, but that's not the date of the gig of course. Ultravox were headline - is this the date that you played with Radio as well on the same line-up?
I suspect its a different gig altogether - which suggests Ultravox played at the Nashville at least twice in November 1976.
They also went on the "Freeze Out" Tour with Eddie and the Hot Rods (and Aswad) 'at the end of the year.'
I've only found two dates so far, both December.
In terms of other dates you might find a use for :-
Neo's first appearance on the Marquee's archive is July 2, 1977 in support of Gloria Mundi (Eddie Maelov's band) and they (Neo) apparently supported Ultravox! there on July 14th.
Hope this helps
