Tickets for the gig at Austin Music Hall in Texas sold out within hours, with Kelly Willis and Bruce Robison also joining the line-up.
Proceeds from the event will be split between the Red Cross, Unicef and Care.
Meanwhile, Gloria Estefan has announced she is staging a concert which will benefit victims of the Asian disaster.
She will perform at Donald Trump's exclusive Mar-A-Lago resort in Palm Beach, Florida, with at least a portion of the tickets being sold for $1,000 (£530) each.
Estefan hopes to raise $100,000 (£53,326) for the Gloria Estefan Foundation, with the money earmarked for the tsunami relief fund.
And singer and songwriter Sting is hoping to raise up to $1m (£533,010) in aid relief at a concert at an Australian vineyard on 10 February.
Owners of the Leeuwin Estate in Western Australia said the star had agreed to play for free after he was forced to cancel a concert in Sri Lanka, one of the countries badly affected by the tsunami.

He was already due to perform two dates there but agreed to play an extra date.
"I got an immediate response from his tour manager with the thumbs up," said vineyard Tricia Horgan.
"I'm not all that surprised, Sting has a reputation for being a real giver."
And musicians in Australia joined together on Saturday night for a concert at the Sydney Opera House, raising money for World Vision's work in the devastated regions.
TV networks united to broadcast the concert and a live telethon, with more than AUS$20m (£8m) pouring in during the event.
'Opportunity to help'
Tim Costello, chief executive of World Vision, said: "In the wake of such a catastrophic disaster, it is wonderful to see so many Australians pull together and give so generously to the victims of this tragedy."
Commercial radio stations in the UK will join together on 17 January for a day-long event dedicated to raising money for the children affected under the banner Radio Aid.
More than 200 stations, including stations run by Capital, Emap and Virgin, among other, will broadcast a single programme between 0600 and 1800 using DJs from the participating stations.
They will also donate a day's profits to the cause.
Celebrities and musicians will also be invited to join in the event, while listeners are urged to donate an hour of their money or time to the appeal.
The UK will also be hosting a large concert on 22 January, with artists including Manic Street Preachers, Eric Clapton and Jools Holland performing at the Millennium Stadium in Cardiff.
'Part of something'
About 65,000 people are expected to attend the gig, with the majority of tickets already sold.
Willie Nelson mobilised his fellow country stars to perform in Texas following a suggestion by local musician and journalist Michael Hall.
"There really are a lot of people who would like to do something," Nelson said.
"We're glad to offer those people opportunities to help out in different ways."
Mr Hall said that he had been inundated with offers from artists wanting to perform.
"People want do it because they want to be part of something," he said.
"They see something so horrible and want to be part of something to make it less horrible," he said.
