Them Mushrooms was formed in 1969 under the original name Avenida Success. By 1972, the group adopted the name that would come to define Kenya’s coastal music scene. The band’s roots were deeply tied to the Harrison family, whose members provided both leadership and creative direction.
Teddy Kalanda Harrison emerged as the founding leader. He played tenor saxophone, provided vocals, and composed much of the band’s music, including their landmark hit Jambo Bwana. His contributions established the band’s distinctive sound and propelled them to regional prominence.
Billy Sarro Harrison played bass guitar and provided vocals, creating the rhythm and harmonic foundation for the group. His role ensured a steady musical backbone, which allowed the band’s melodies and solos to flourish.
George Zirro Harrison performed on guitar and also contributed vocals during the band’s early years. His work added melodic complexity and enriched the group’s live performances. He eventually left the band, but his early contributions helped shape its identity.
John Katana Harrison handled keyboards and vocals. Over time, he took on leadership responsibilities, particularly after the departure or passing of key members. His guidance maintained continuity in the band’s direction and performances.
Dennis Kalume Harrison served as the band’s drummer. His rhythms underpinned the group’s fusion of coastal sounds, providing the essential beats that drove their performances. He remained part of the band’s formative years before his passing.
Them Mushrooms began performing at beach hotels in Mombasa, where they cultivated a following among tourists and locals. Their fusion of Chakacha, Benga, taarab, and reggae set them apart from other bands in the region.
Their music blended traditional Kenyan rhythms with contemporary influences, helping the group appeal to both local audiences and international visitors. This combination of sounds became a hallmark of their identity.
The release of Jambo Bwana in 1982 marked a turning point for the band. The song became a defining hit, widely recognized for its Swahili greetings and the phrase hakuna matata.
The success of the song brought Them Mushrooms regional fame and established them as cultural ambassadors for Kenyan coastal music. It was widely played in tourist venues and covered by other artists.
In the late 1980s, the band relocated to Nairobi. This move expanded their audience and allowed them to engage with Kenya’s broader music industry while continuing to perform coastal rhythms.
Over the years, additional musicians joined the band. Henry Ndenge Saha played drums and provided vocals, while Freddy Awalla Onyango contributed guitar and vocals, strengthening the band’s melodic and harmonic depth.
Dickson Owour Onyango added trumpet and vocals, further enhancing the group’s sound and giving their music richer texture. These additions allowed Them Mushrooms to maintain a full and dynamic live performance presence.
The band’s lineup stabilized around surviving original members and key later contributors. John Katana and Billy Sarro continued to anchor the band, preserving the musical traditions established decades earlier.
Teddy Kalanda Harrison remained a central figure until his death in February 2026. His legacy as a composer, saxophonist, and vocalist left a lasting imprint on Kenyan music and the global recognition of Jambo Bwana.
Today, Them Mushrooms continues to perform, blending original and later members. Their enduring presence reflects a commitment to the sounds of Kenya’s coast and the ability to inspire new generations while honoring a rich musical legacy.
