I've managed to come up with a double connection for this week's Star Track.
Sky Arts channel have been showing the CNN 'Soundtracks: Songs that Defined History' 8-part series released last year. As you'd expect it's an American view of 20th Century history involving Civil Rights; Vietnam; 9/11; Katrina; Berlin Wall; Space Race etc. Many poignant moments remembered by certain songs and it gives me an excuse to repeat a quote, I like, by Kix Brooks (of Brooks & Dunn) who says: 
"I don't know if music can really change the world. But it certainly gives us a real powerful spirit while we're doing our best to do so."

From the 'Berlin Wall' programme there was the German band Scorpions who wrote a song in 1990 celebrating glasnost and the end of the Cold War. It has a guitar sound similar to that of Pink Floyd on 'The Wall', which might be deliberate as the video does show a snippet of 'The Wall' concert. The song topped the charts in Germany and across Europe and peaked at number four in the US in August 1991 and number two in the UK and to date has over 616 million views on YouTube. 
The Berlin Wall came down in June 1990. Scorpions 'Wind of Change' taken from the album 'Crazy World' was released in November, one month after my son Scott was born - who's birthday it is today.
