I just found out that a "roman candle" is
"a type of fireworks, with long, thick paper tubes that contain layers of "stars" and lifting charges.
A roman candle is constructed by the following method:
load a layer of bentonite into the tube to close off the end.
load a layer of lifting charge.
load a pyrotechnic star.
cover the assembly with a dusting of black powder.
load a layer of delay powder.
repeat until tube is full
There are several variations on this:
Many Chinese roman candles use clay instead of delay powder and run a length of fuse down the inside of the candle to time the lifts.
Larger roman candles will usually add more lift to the highest layers and less to the lower layers in order to cause the stars to lift to the same altitude.
Some really large candles will load comet shells instead of stars.

For the longest time I thought that Bono, in "promenade" was referring to the Italian city, but this makes a lot more sense!!!!
