There is already answer to the voice message question, good! Yest, this is the official Radio Moscow broadcast announcing his flight. There are no report of Gagarin actually hearing it - but he had all capabilities on board for it, and so do you.
In Russia, everyone from the older generation knows this broadcast. For the announcer himself (a very famous person in the USSR, official voice of the Kremlin for many decades, with lots of important announcements under his belt) the two most memorable in his whole life were - this one, and the message about the final victory over the Nazi in the WWII.
The second one, the 'Vovan" reference is our "special thank you" to a very knowledgeable and helpful guy who gave us the most detailed and accurate data for this surrealistic gantry.
For the music... I don't even remember all of the songs myself. I tried to come up with the few most representative from all geographical and cultural areas of the planet, trying to find music not necessarily written in the same year (could be much older), but sufficiently popular in that time frame. Cutting the fragment long enough to recognise but hopefully short enough to not to run into any infringement problems. I hope there are no anachronisms, but can't be sure for the more "exotic" parts of the world... It looks like "find this song" is now becoming another quiz fun with the addon
.
As for the "eggs", I think only one is left, and it is not so much of an egg... I'll post about it a little later today, as it takes some more elaborate description...

Now, 13 April is a perfect date to try some fun with the emergency ejection scenarios. If you already tried one, you probably realized that, with so many huge and unforgiving obstacles around the launch pad, ejecting safely is only half of the deal - you have to land safely as well!
Luckily, the corridor along which the ejection seat flies in the rocket's nominal launch azimuth is actually the safest. In many and many test ejections during development (for the testing, you don't necessarily have to wait for the explosion - you can eject at any time by the Ctrl+A keys) and with all random wind variations, I only had a single misfortune with the spotlights tower.
However, if you start experimenting with different pre-launch rocket orientations, and "shooting" a cosmonaut is other, not-so-friendly directions (hint: you can change the RING parameter for the launchpad in the scenario file for that, to any value between 0 and 1) - parachuting to safety may become more dangerous...
