Unlike the other three tracks on Pet Shop Boys' 'Agenda' E.P 'The Forgotten Child' shrouds its lyrical content in mystery as well as being an achingly beautiful ballad rather than a dance track. This is Neil Tennant at his deepest - you could listen to the lyrics over and over and come up with a different interpretation every time. Whilst 'Agenda' is a politically themed release this track could as easily be about Madeleine McCann as it could be about children caught up in a refugee crisis, Trump's wall or Brexit. That's one of the joys of Tennant's penmanship - you can spend hours searching for hidden depths amongst his best work, and this is up there with that best. Chris Lowe lays down poignant backing designed to pull at the heartstrings, with drums only entering the soundscape near the end. If there's one criticism it's that it's too short - this would benefit hugely from an extended mix that allows the instrumentation to breathe. Ex-Xenomania member Tim Powell makes a fabulous fist of production duties - this track is lush and on a half-decent system envelopes the listener. 'Agenda' as a whole has been a revelation, with 'The Forgotten Child' and 'On Social Media' standouts that prove in the autumn of their career Pet Shop Boys still have the capacity to surprise, delight and move.
