I've been to two weddings that did this. One had about 100 guests, one had about 150. There were several "helpers" lighting sparklers, but there were so many people and so much coordination trying to get people to stand in two lines that 1) people were confused and 2) not everyone's sparklers were lit at one time so it kind of defeated the purpose. It wasn't a bad thing, it was just kind of a "why?" thing. They might have gotten 1 or 2 cool pictures, but as a guest it was just annoying.
Also, synthetic wedding attire + alcohol + party + lots of people + sparklers/fire makes me worry about:
while i appreciate the concern, the question i asked is about music choice. not whether or not i should be doing sparklers. I have been to muliple weddings that have the sparklers and everyone that I know has loved it. This is what I picture for MY WEDDING.
You will probably need a few songs, my experience is it takes awhile to get everyone situated, sparklers lit and then a few passes for photos. You'll alway need the long sparklers, not the short ones. I'd pick 3 or more songs so people don't get bored
ETA : In my experience - I didn't have one bc in my experience they are difficult and photos never turn out as planned.
