For those of you heading to Punchestown on Sunday for a second dollop of AC/DC this year, here are some things you'll need to know:

Car Parks open at 2pm
Gates open at 4pm
Show kicks off at 5pm sharp

The Blizzards will start the show at 5pm in place in Thin Lizzy, who have been forced to cancel their support slot because drummer Tomm Adridge broke his collarbone in a cycling accident at the weekend. The Blizzards will be followed by the The Answer, then AC/DC themselves.

Those who buy four or more tickets from ticketmaster are entitled to a free parking pass, while those with less than four in a car can purchase a parking pass for €30. Those driving are urged to buy a parking pass in advance as space is limited, and to leave at least three extra hours for travel time to and from the venue. There will be a 90 minute delay exiting car parks as buses will be given first priority. Sounds like a bag of laughs, I'm with the gardai - take the bus!

Dublin Bus will be running services to and from the concert. Tickets are available from the ticketmaster and Dublin Bus websites.

The rest is the usual - don't bring drugs, drink or any sharp pointy things, remember your wellies as well as your suncream, cooperate with stewards and follow loudspeaker announcements.

Plan you route according to which carpark your pass is for (red or blue). For directions visit mcd.ie or check www.garda.ie for full details of their traffic management plan.
