After watching images of late stars like Tupac Shakur and Michael Jackson beamed onto stages in America in recent years, Garcia's daughter Trixie admits she was intrigued by the technology and considered conjuring up a lifelike image of her dad for fans at the Grateful Dead's Fare The Well shows.

She tells, "We came very close to making the Jerry hologram. I met with people and was very interested in trying to make the Jerry hologram where he appears for a couple seconds - like a rainbow.

"It just didn't work out. It was too much."
