The cream of Harrow's vocal talent gathered in a socially-distanced Speech Room before half term to compete in the annual Glees and Twelves competition.
The event sees each of the 12 Houses select two groups of boys. The first is the Glees who will choose a song and sing it in an unaccompanied close-harmony arrangement.
The Twelves is a larger group of boys who perform a unison song of any style with piano accompaniment.
This year's hotly-contested competition saw entries which included The Beatles' Yesterday and Billy Joel's Piano Man.
The event was judged by David Hill MBE, Musical Director of the Bach Choir.
