Bollywood singer Kumar Sanu has struck a wrong note with his show in Kathmandu, with one hospital saying it was not a beneficiary of the fund raising as had been claimed.

Kumar Sanu, who entered the Guinness Book of Records by recording 28 songs in a day, came to Kathmandu last week, reportedly to raise money for three organisations.

While two are charities for orphans and dumb children, the third institution supposed to have benefited from his two concerts in Kathmandu was the Bhaktapur Cancer Hospital in Kathmandu valley.

On Tuesday, nearly 48 hours after the singer's departure, the Bhaktapur Cancer Hospital issued a statement saying it had no connection with the supposed fund-raiser.

The hospital also said it has filed a complaint with the district administration office in Bhaktapur.

Neither the organisers nor Sanu could be contacted for their comment.

Sanu told the media he had earlier sung at a concert in West Bengal, helping raise funds for tsunami victims.

The singer's trip to Nepal started on a sour note when he fell out with the organisers of the shows and threatened to pull out.

According to Sanu's entourage, the organisers, a Nepalese NGO called Hamro Nepal that has earlier put up programmes to celebrate Nepalese Crown prince Paras' birthday, had not been playing by the rules.

They said they had not received the money they were promised and their musicians had been given only a one-way ticket to Kathmandu.

They also said Sanu had promised only to take part in one show but the organisers advertised a second soiree at the five-star Yak and Yeti hotel where the tickets cost much more.

That dispute was resolved at the mediation of Nepalese music director Sambhujit Baskota.
