Viens, on rêve – Imagine for Margo’s Charity Single
To celebrate its 15th anniversary, Imagine for Margo is releasing “Viens, on rêve”, an unprecedented charity anthem bringing together nine artists: Vitaa, Claudio Capéo, Tété, Cali, Daysy, Éloïz, Nyv, Adam La Nuit and John Mamann, who also co-wrote and composed the song alongside Laetitia de Lucas and Mathieu Llech. Available on all major streaming platforms, this uplifting pop and Afro-inspired track has one mission: to amplify the voices of children and teenagers affected by cancer and support childhood cancer research.
Childhood Cancer: An Overlooked Public Health Challenge
In France, seven children are diagnosed with cancer every day, representing approximately 2,500 children and teenagers each year.
Cancer remains the leading cause of death from disease among children and young people, both in France and across Europe.
For 20% of these young patients, no suitable treatment is currently available, while two-thirds of survivors experience serious long-term health complications.
For 15 years, Imagine for Margo has been fighting to change these figures.
Yet the reality of childhood cancer remains largely unknown to the general public.
To raise awareness and turn this major public health challenge into a nationwide movement capable of reaching millions of people, the association decided to use the power of music.
The result is a national charity anthem designed as a celebration of hope, a call to action against childhood cancer, and a message of solidarity for every young person fighting the disease and their families.
“Viens, on rêve”: A Charity Anthem Featuring Nine Artists
The song was born from a collaboration with John Mamann, a French singer-songwriter who has previously supported charitable initiatives, including the 2024 Pièces Jaunes charity anthem, “Les p’tits soleils”.
Together with Laetitia de Lucas, John Mamann wrote the lyrics, drawing inspiration from Margo’s story and the courage of all young people facing cancer.
To bring the project to life, Imagine for Margo partnered with S2R-STARBRAND, a communications agency specialising in collaborations between artists, talent and brands.
Alongside John Mamann, eight other artists generously contributed their voices and talent to this uplifting pop and Afro-inspired track:
Vitaa, Claudio Capéo, Tété, Cali, Daysy, Éloïz, Nyv and Adam La Nuit.
Nine voices, one shared belief: no child should have to face cancer alone.
These artists wholeheartedly answered Imagine for Margo’s call to shine a spotlight on the fight against childhood cancer and help turn the dream of a world without childhood cancer into reality.
LISTEN TO THE SINGLE
From Margo’s Fight to “Viens, on rêve”
Behind this song lies an extraordinary story : that of Margo. Born in Johannesburg in 1995, Margo’s courageous battle against brain cancer inspired the creation of Imagine for Margo.
During her illness, she launched an online fundraising campaign to support medical research.
Her initiative raised an incredible €103,000, making it the largest private online fundraising campaign ever organised in France at the time.
Margo passed away at just 14 years old.
In her notebooks, she left behind a sentence that would become Imagine for Margo’s guiding motto:
“Go, Fight, Win, and always make your dreams come true!”
It is this spirit of hope, determination and solidarity that “Viens, on rêve” embodies.
The song’s vibrant pop and Afro-inspired sound is no coincidence. It reflects something of Margo’s roots and her joyful, courageous outlook on life, even in the face of illness.
