Template:Studio appearance row
From PickiPedia: A knowledge base of bluegrass, old time psychedelic jams, and other public domain music
Formats one row of the query behind Template:In the studio. Not for calling directly.
It emits record||track||number||instrument, which
Module:Studio sessions then groups by record. The double pipes are a
separator the values themselves cannot contain: a track title may hold a comma
or a dash, and grouping on either would split "Swords to Ploughshares" in half.
