AS PART of Museums at Night, Abbot Hall Art Gallery opens late tomorrow (Friday, 6.30pm-11pm) with live music by Paper Cranes (pictured), open-mic poetry from Kim Moore plus lots of other activities. Pizza Principles will be taking along its wood fired pizza oven, so everyone will get a free slice as well as a free drink in the Kendal gallery's pop-up bar. Standard gallery admission applies (students free).
