Otherwise known as 大闹天宫 (Da Nao Tian Gong). This was shown on television just about every year during the Lunar New Year when I was a child, and was a favourite of mine.
Found out there was a DVD release in 2004 but did not manage to find a copy of the 40th anniversary edition for sale on eCommerce sites. The cover of the standard edition is just… butt ugly.
Finally managed to snag a new copy on eBay, for only S$25. Just look at that beautiful packaging. The character art sheets are a very nice touch. The video quality is a disappointment though. Scratches, dust, even some pen marks are visible. Obviously there was no effort made to clean up the source.
That said, this is probably the best that is available at this point of time, and I am very happy with this purchase.
