It was a case of deja vu last night for the long-suffering residents of Salou, the northern Spanish town where thousands of British students flock every spring for four nights of drunken debauchery.
For the twelfth time, the Costa Dorada resort has been overrun by Saloufest, the notorious annual sports tour returning for another round of hard drinking, half-naked partying - and the odd day of volleyball or hockey.
The first pictures released from this year's event paint a familiar picture: packs of fresh-faced revellers in proudly ridiculous fancy dress, their flesh largely bare and arms aloft as they stagger and bellow through the streets.

The first 5,000 of a total 8,200 people are said to have made the trip from Britain's universities yesterday, marking an increase of 1,000 on last year.
Police say the first night of the tour passed without any arrests being made - but past form suggests they won't be holding out much hope for an easy ride.
Last year's event saw officers launch a crackdown on any students caught drinking in public, putting an end to the days when the locals would turn a blind eye to those flouting Salou's alcohol bylaws.
The town also decided to uphold rules preventing the Saloufest partiers from roaming around town half-naked.
The 2011 tour saw two toga-wearing students hauled off to a police station and fined £265 for breaking the alcohol laws.
This year the local authorities have handed out leaflets warning British visitors not to drink on streets and beaches, while those found stumbling around shirtless can expect to face the consequences.

Spanish media reports that ILoveTour, the firm that organises the festival, has some 30 supervisors on hand to babysit the horde of 18-to-23-year-olds.
One account, from Spanish newspaper El Pais, talks of streets streaked with vomit and urine, disoriented youths, deafening noise and riot vans on standby.
Despite local opposition, hoteliers in the area support Saloufest because it extends the holiday season and is timed so as not to interfere with the influx of Easter tourists.
In an effort to keep the peace, some of the seven hotels set aside for the event have opted to separate their British guests from other holidaymakers.
The basic festival package sees students shell out £189 for coach travel and four nights in two-star accommodation, with optional extras including day trips to nearby Barcelona and Port Aventura.
