Hi,
It looks like some of the Sleep Radio songs have been re-recorded and the earlier versions are disappearing. In particular, the synth / keyboard version of 'Lulla Lullaby' no longer seems to be in rotation, with only the version played by actual instruments remaining.
Is it possible to get this earlier version? Is it on any of the yoto cards? Can the earlier version be added back to the Sleep Radio rotation? It is one of my kids favorites.
