When Greg Hall and Morgan Matens met and fell in love as graduate students over a dozen years ago (he was studying library science; she was studying set design), they had no idea they’d wind up working together. Hall is now children’s librarian at Nashville Public Library (NPL), where Matens is a puppeteer with Wishing Chair Productions, NPL’s in-house puppetry troupe. Sheltering in place together, the couple has collaborated on weekly Facebook videos that bring NPL’s puppets to families across the country. The runaway hit so far is the music video “Curbside Baby,” set to Vanilla Ice’s “Ice Ice Baby” and featuring a DJ mouse who raps instructions for curbside library services.
