Out of shot in Juliana's photo are imposing balconies which flank the hall, giving it the feel of a posh galactic senate from Star Wars. They're quite impressive pods despite their failure to levitate or contain Natalie Portman.
It's fair to say most of the crowd were more familiar with Evan and the Lemonheads material. Expecting everyone to know a Madder Rose cover from a Blake Babies album is perhaps too ambitious!
Juliana's songs were well received though - notably her excellent takes on 'Ugly' and 'I Picked You Up' (a request earlier in the day on Twitter), together with the one most people knew - 'My Sister'. She grew into the performance as the night went on, taking inspiration from the venue rather than being intimidated by it.
Craig's sidebar: I took a friend along for their first Hatfield experience. Afterwards I was asked which of Juliana's albums I would recommend. We may have a convert! Also, hello to Lieve, Carsten and Charlie who I spent some time with. It was great to share the evening with you.
Surprisingly there were a few negative comments on Twitter from a handful of people who clearly went with very different expectations to the type of show these two have been performing in recent years. These views appear unrepresentative of the overwhelmingly positive atmosphere in the hall.
Juliana is a highly talented singer and guitarist performing songs which many of us have a long standing emotional attachment to. Evan's songs were effortlessly performed showcasing his talent as one of the most gifted songwriters of his or any generation - Juliana saying as much with an impromptu compliment to her partner during the set.
What's not to love?!
Evan and Juliana winging it as they go along is rather charming - someone commented that it was like watching talented teenagers jamming in the bedroom.
When they returned for the encore their lack of clear planning was even more evident. A late crowd request for 'Rain' was picked up by Evan and nearly paid off as he looked to Juliana for her consent. There's every chance this unrehearsed song so reliant on harmony might have come off as shambolic, but it's a chance a lot of us would have been happy to take.
Instead, Juliana decided that this was her time to say her goodbyes to London, leaving Evan to close the show on his own with what remains the finest Lemonheads cover song.
Mrs Robinson? Mrs Shmobinson.
No, of course it was 'Different Drum' - an odd but somehow fitting end. Evan and Juliana may appear to travel to a different beat yet there is a beautiful connection, enhanced by 25 years of exceptional songwriting.
It was a privilege to witness and for many of us in the crowd there's no other place we'd have rather been.
