A new version of the Treehouse song has been recorded as EACH aims to raise £3m for a new hospice in Ipswich.
The original song was released in 2005 by Swedish group I'm From Barcelona who have over 20 members.
The lyrics have been changed to fit in with the appeal and it features children and staff from the hospice.
You can listen to the song on this page and on a free DVD which aims to introduce school children to the work of the hospice and fundraising.
"It's all about making music with the children," said Ray Trevasso, music therapist at EACH Ipswich. "It brings a way for life-limited children to express themselves in a way that using words can't."
The original Treehouse song was chosen by BBC Suffolk as the 'theme tune' of the campaign to replace the cramped East Anglia's Children's Hospices bungalow on Walker Close, Ipswich with a state-of-the-art facility off Felixstowe Road.
Andrew Rayner, who knew someone at EACH, was drafted in to record the new backing tracks at his home studio.
He's also produced music for church groups and is music director at Christ Church in Felixstowe.
"It's great fun and, when we're working for a cause as fantastic as this, then it's just great trying to build everyone up to get them to do their very best.
"They always say that if you smile when you're singing then you always get that feeling of the positive-ness of what's being sung.
"We've recorded a version of the song that's buoyant and really got that summer feel, and that's what we've been trying to get."
Find out more about the DVD on the
EACH Treehouse Appeal
website. Free copies are available for schools and any other organisation or individual.
The song isn't available to buy on CD or download.

From Camden to music therapy
Ray Trevasso is the regular music therapist at EACH Ipswich. Ten years ago, he was working in schools in the capital when he had a realisation.
"When I was in bands we were gigging in Camden and the rest of it and all I dreamt of was getting a record deal.
"As a day job, I was working as a music tutor in schools in east London with kids who were struggling with education or involved in gang culture.
"I realised I got more out of seeing those kids get something out of music than I was getting out of my own bands."
Ray then did a masters degree in music therapy with the Nordoff-Robbins Centre and now works at EACH's bungalow in Ipswich alongside trying to set up a Suffolk music therapy service for schools to use.
At the bungalow, they have various instruments including a full drum kit, an Irish harp and songwriting computer software.
A life-limited child can work on music with their brothers, sisters or any family members.
"Music is a great leveller - we're all there together and that's what the whole ethos of the hospice is really," said Ray.
"Hearing is one of the first senses we get before we're born and it can be one of the last to go before we die - and that's why music is so important."
Jo Vise had never been at a proper recording session before
BBC recording session
In April 2010, Andrew and Ray came to BBC Suffolk to record the vocals for the Treehouse song with help from BBC engineer David Butcher.
The lead vocalist was Jo Vise who works as a nurse with an EACH child.
"Children that have got very limited communicative ability - when you see them react to music, it's really worth it, it's really good," she said.
"The thing about the song is that it's really easy to pick up. It's a really bouncy song and the chorus is really bubbly. I really like it."
Six children - Rene, Donnell, Chloe, Rebecca, Lydia and Megan - nurses, parents and BBC Suffolk staff got together to record the backing vocals.
Melanie Chew, EACH fundraising director, was also there and looking forward to getting the DVD out into schools.
"Sometimes the EACH message is a very difficult one to get across to young people," she said.
"It's a very joyful way of getting across what it is the hospices do so that other children can enjoy it and get motivated to join in the Treehouse Appeal."
BBC Suffolk is helping East Anglia's Children's Hospices raise the £3m needed to build a new children's hospice in Ipswich.
