Having read through these Chelmsford Calling pages, you may like to tune in to a radio station playing similar music to that heard on Chelmsford Calling.
I highly recommend you listen to Angel Radio by clicking on the link / logo below. Angel Radio is mentioned elsewhere on this website & also on the links page, but in case you miss this, below is a direct link to their website from where you can listen to their broadcasts.
Angel Radio is probably closer to the original ethos of Chelmsford Calling than what Chelmsford Calling was ! Top marks to Tony & Martin & their dedicated team, - & long may they continue.
There are in fact many stations on the internet that play music & comedy from the 1930's - 1950's era. Here's a link to another good station I found recently - Radio Carousel.
