For anyone of a Druidic bent, the Solitary Druid Fellowship has its liturgy for Lughnasadh/Lammas/etc. up. I'm not doing it quite yet (it's not time) but I wrote out my adapted script; I will be honoring Lugh and Tailtiu. (Current plan is to honor Gaulish gods at the solar festivals, Irish gods at the fire festivals.)
BTW, SDF is Indo-European Druidry (affiliated with ADF) so not just for the Celtic-focused. Just FYI.
