His upcoming concert has become Singapore's fastest-selling show ever.

Within a day, 80 per cent of the 8,700 tickets were snapped up, said concert promoter Hype Records.

This translates to 6,900 tickets, priced between $78 and $198.

Sistic chief operating officer Kenneth Tan told The New Paper that the concert 'broke all previous records' at the ticketing agent.

The number of transactions on the first day was an 'unprecedented high' and 'almost 100 per cent more than the previous record holder'.

On the flip side, the surge in demand caused tempers to flare as many fans got frustrated in a mad rush to get the best seats.

The sense of urgency is understandable, as it has been three years since Jay's previous concert world tour. He last performed here in November 2004.

The 28-year-old singer-songwriter is slated to release his new album Jay Chou On The Run on 2 Nov, and record shops have started taking orders for it.

According to some fans, the Sistic server 'crashed' and 'kept hanging' from the moment online ticket sales started at 9am, and the hotline that started at 10am was constantly engaged.

Ms Chen Weiling, 28, said she spent the whole morning trying to get through to Sistic and even got her colleagues in the office to help, but to no avail.

'It looks like the system cannot support such a high volume,' she said.

'The Sistic fee has already increased 100 per cent from $1 to $2, but did Sistic invest in a better system or get more IT support to cope with the big volume?'

In the end, the finance analyst had to make a trip to the Sistic counter at Tiong Bahru Plaza during her lunch break. And she queued for more than an hour to get her tickets.

'There were only seven people in front of me but I still had to wait so long,' she said.

'It's frustrating because you're losing time while other people are booking their tickets, and when your turn comes, all the good seats are taken up.'

Ms Chen ended up with a $138 ticket, though she had intended to buy the most expensive $198 ticket.

Merchandiser Gladys Kuek, 27, also got a $138 ticket instead of the $198 one she had wanted.

She said: 'It's disappointing because we waited so many years to see Jay's concert but we can't even get good seats.'

When asked, Sistic's Mr Tan insisted that 'technically speaking, our system did not crash'.

But the system allows a 15-minute grace time for every seat to be accepted by a potential customer, so others in the queue would have to wait, he added.

Hype Record's artiste and repertoire director Jonathan Tan said his company was 'flooded with phone calls' from irate fans who could not get through to Sistic.

His company has contacted Jay's management to 'explore the possibility of a second show'. He said 18 Jan is a possible date, as the Singapore Indoor Stadium is still available for booking.

And it has been confirmed that the second show is on the 18 Jan and that is his BIRTHDAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ARRRRRRRRRRRRRRRRRRRRR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I ALSO WANT TO GO ON HIS ACTUAL BIRTHDAY AND CELEBRATE WITH HIM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
