Hi Kent - thanks for the swift reply.

The connection script worked - thanks

'''
pi@moode:~ $ sudo /var/www/util/blu-control.sh -C A8:99C:52:19:C4
** Connecting to device A8:99C:52:19:C4
** Device A8:99C:52:19:C4 connected

But on reverting to the GUI and pressing play, I get the error message "Failed to open "ALSA Bluetooth" (alsa); Failed to open ALSA device "_audioout": No such device"

So perhaps the failure is not in the connection itself, but somewhere between connection and BT player.

As per the OP, connecting via bluetoothctl works.

Best
