Mendis appeared on the popular BBC television music programme "Top of the Pops" with his singing partner Sandra Edema in 1968 as guest artists with his song "Feel like a Clown". The B-side of the record "Rainbow Land" was the A-side in the States and today (2013), it has become a collector's item in the Psychedelic Rock community in the west. They were also featured with the song on "Beat Club" in Germany that year. Eugene Wright, bass player with the original Dave Brubeck Quartet, arranged and recorded five of Mendis's songs with only him playing bass. He also arranged and produced one other song, "Singing Fish", with electric guitar, bass, and piano. They were sung by Sandra Edema.
