Is there any paper trail or proof that any of the money went to the folks who needed it?

I don't know....UNICEF is the UN, after all, and they're STILL collecting in the name of Harrison and the concert:

Here ya go....Harrison paid $1 million to the IRS out of his own pocket:
Album, video and ticket sales yielded over USD 9 million. Unfortunately legal and tax problems stopped the money reaching the needy till 1981. He paid the final tax bill of over USD 1 million from his own pocket. The concert was also risky as many western nations, especially the US, supported Pakistan against Bangladesh.
However, the concert itself did much for the independence of Bangladesh. It greatly increased public awareness of the war and the growing famine. It generated a tremendous amount of goodwill and active support for the cause of Bangladesh.
