This year's Boston Secular Solstice will be on Saturday December 28th, and again I'm organizing the music. Are you interested in singing or playing? A wide range of instruments work here: in the past I think we've had people play piano, flute, guitar, mandolin, and cello. This isn't a large time commitment: we typically meet once or twice before the event for an evening to run through songs.
Here's something I wrote up about last year, with links to the songs we did: Boston Solstice 2023 Retrospective.
We haven't finalize the song list yet, but the current draft is "Always Look on the Bright Side of Life", "Battle Hymn of the Rationalist Community", "Brighter Than Today", "Endless Lights", "Find My Tribe", "Gather Round", "Give My Children Wings", "No One Is Alone", "Old Devil Time", "Somebody Will", "The Circle", "The Mary Ellen Spider Song", "We Will All Go Together When We Go", "When I Die", "When I'm Gone", and "You've Got A Friend In Me".
Let me know if this sounds fun!
