It's Sunday (we're told: who can tell any more?) so it's time for another trip around the TBS archives with our #SundaySession! https://soundcloud.com/transdiffusion/the-transdiffusion-sonowaltz-welcome-to-transdiffusion

We'll start this #SundaySession at the beginning - almost literally - with the Baird Television March from the early 1930s. This was later used by Gaumont-British for their cinema newsreels. https://soundcloud.com/transdiffusion/baird-television-march

Since we're starting with early stuff, here's another early one: Associated-Rediffusion starts the day on 22 September 1955. Leslie Mitchell is here to tell you what's what in stern tones. #SundaySession https://soundcloud.com/transdiffusion/associated-rediffusion-day-one

Sticking with Associated-Rediffusion, here's their own march from 1957. Redvers Kyle is your announcer. #SundaySession https://soundcloud.com/transdiffusion/associated-rediffusion-march

This one is also available as a recreation in vision thanks to @KecskeBak, plus more information from @kiffr... #SundaySession https://www.transdiffusion.org/2015/09/22/rising-star

North of the border (and Border) now for ITV's longest-lasting startup music, as Geraldo presents Scotlandia. #SundaySession https://soundcloud.com/transdiffusion/scotlandia-1

Transdiffusion's #SundaySession will be back after the break. https://soundcloud.com/transdiffusion/nothing-tastes-like-butter

Welcome back. Time to start ABC Weekend's Sunday before the Morning Service with the austere Pastoral Prelude from Frederic Curzon. John Benson is on hand to do the authority announcement as always. #SundaySession https://soundcloud.com/transdiffusion/abc-morning-service-startup-using-pastoral-prelude

When ABC weren't starting up for a church service in the 1950s, they let their hair down with Mr Punch from Robert Farnon. #SundaySession https://soundcloud.com/transdiffusion/abc-1956-9-start-up-mr-punch

Back to Sunday mornings before the church service on ITV and London Weekend opens with something less swinging and groovy than their usual daily musical offering. #SundaySession https://soundcloud.com/transdiffusion/london-weekend-sunday-morning-service-opening

Meanwhile in the south-west, TSW started each day in the early 1980s like this... #SundaySession https://soundcloud.com/transdiffusion/tsw-starts-the-day

By the way, every single piece so far in this thread has been one that @kiffr can't bear. So, just for him, it's over to ATV and a piece he really loves. #SundaySession https://soundcloud.com/transdiffusion/sound-and-vision
