I Will Have to Consolidate All of This Sooner or Later

Do have a page with venue information. If you're SFS or SFO and you perform in one place, just put the address on the home page and on various second-level information pages.

If you're a small chorus or orchestra (Cal Bach, Philharmonia Baroque, NCCO) that performs each program in three or four locations, have a Venues page with an easy-to-find link on the home page.
