Here's a few jingles to whet your appetite.

Peaceful hour
The classic 'Peaceful Hour' jingle that makes you think of the 'Lonelyhearts' feature.

Radio City on 194
A slow and mellow jingle.

Drums 194
A fast drum intro into a sung 194 Radio City.

Bill Mitchell 194
The classic deep v/o Bill Mitchell, used for a number of City jingles. In this case the 194 with stabs.

Brightlights Downtown
Slow 'Downtown' jingle.

Arlon Green
Sounds like Elton John but this was a jingle recorded by Arlon to promote his record. Unfortunately it didn't help to boost his career……..have you ever heard of him?
(thanks to Brian Jones for this information)

Heart of Liverpool song.
These were the days when you had full length songs as jingles (not any more).
From 1977-79, this classic jingle lasts for over a minute and listen to the bass, it's just so cool.

Get Out of Bed
and shake a leg with Norman Thomas.
Just a little bit different from saying it's the Norman Thomas breakfast show.
