The Mirror reports that Maurice Phillips, who is married to the superstar's sister Tyka Nelson said: “I was with him just last weekend.
"He worked 154 hours straight. He was a good brother-in-law.”
Those who had gathered outside the late singer's memorial service wer given the present, which was filled with a mix of tour t-shirts to tour booklets - but no fan got the exact same gift.
