Organisers of the tsunami fund-raising concert at Cardiff's Millennium Stadium hope the £1.25m collected could still rise in the coming weeks.
There are hopes that a commemorative CD and DVD could be made available.
Workers at the stadium are continuing to dismantle the stage after Saturday's mammoth concert, in preparation for the forthcoming rugby internationals.
Stars including Keane, Snow Patrol, Manic Street Preachers, Eric Clapton, and Lulu performed free of charge.
The seven-hour gig was the biggest event of its kind in the UK since Live Aid 20 years ago.
The stadium is now being turned back into a sporting venue. The pitch is about to be laid ahead of the spring rugby internationals. The Wales v England game takes place in less than a fortnight.
Meanwhile, 14 officers with South Wales Police leave for Thailand on Monday to join the effort to recover and identify the bodies of victims of the Tsunami disaster.
They are all volunteers and have been trained to help them deal with traumatic conditions.
The officers are expected to stay in Thailand for two weeks.
Saturday's fundraising concert was organised in just three weeks.
Paul Sergeant, the stadium's general manager, paid tribute to the "phenomenal" response of the 61,000 music-lovers who bought tickets for the event, and the thousands more workers who volunteered to make it happen.
The £1.25m raised on the day is on its way to the Disaster and Emergency Committee, bringing the total raised by the British public for the disaster so far to over £200m.
But Mr Sergeant said he expected the figure to increase. One way of raising more funds would be to release a CD and DVD of the entire concert, and Mr Sergeant said they would be "exploring the idea".
Live Aid's Midge Ure made a surprise appearance at the gig
He said : "Everyone, from all the international artists who offered to play for free, to the production teams and countless volunteers, went flat out to make sure that the event was a day to remember as well as a massive fundraiser.
"We had a world-class line-up for what was a world-class event."
Welsh musical stars including the Manic Street Preachers and Kelly Jones of the Stereophonics - who was touring in France, but flew in just for the event - helped make the concert a sell-out. Singers Charlotte Church, Aled Jones, and Katherine Jenkins, also took part.
But there was also support from UK stars like Lemar, Lulu, Jools Holland and the legendary guitarist Eric Clapton.
Scots singer Lulu said it was an "amazing, amazing event" . She said the "energy coming from the audience helped to make the evening really special".
Video messages of goodwill were played to the rocking stadium audience - from figures as diverse as Tony Blair and Welsh First Minister Rhodri Morgan to Sharon Osbourne and Mark Hughes, the former Wales football manager.
It was an 'amazing, amazing event' according to Lulu
Live Aid co-creator Midge Ure made an unexpected appearance, paying tribute to the skill of the organisers in arranging the event in such a short space of time.
As well as the 61,000 fans who were in the Millennium Stadium millions more joined in the show on TV, radio and online.
Richard Jones of Oxfam Cymru said the event had "put Wales on the map".
"It has really ingrained in out minds that this kind of poverty, this kind of suffering does exist, " he said.
"The real challenge now is to see that it does not happen again".
