Radio Dikke Betta (Big Bertha) on 1620AM with what sounds like a selection of traditional, Dutch folk tunes and more modern music. Started hearing them from around 2112z, though I would think they were on long before that - exceptionally strong reception on the east coast of the UK.
2147z - "You Ain't Seen Nothing Yet" by Bachman–Turner Overdrive
2158z - station ID?
2237z - "Locomotion" (not sure which version of the song is being sung)
