U2 Concert in 17 Mins!!

This has been posted before I know!!! .. But does anyone have the best
solution to that problem about the 4 boys trying to cross the bridge to get
to a concert in 17 mins?? ... if you forget here is the puzzle...

>"U2" has a concert that starts in 17 minutes and they
must all cross a bridge to get there. All four men begin on the same
side of the bridge. You must help them across to the other side. It
is night.
>
>There is one flashlight. A maximum of two people can cross at one
time. Any party who crosses, either 1 or 2 people, must have the
flashlight with
them. The flashlight must be walked back and forth, it cannot be
thrown,
etc. Each band member walks at a different speed. A pair must walk
together at the rate of the slower man's pace:
>*Bono: - 1 minute to cross
>*Edge: - 2 minutes to cross
>*Adam:- 5 minutes to cross
>*Larry: - 10 minutes to cross >
