Wham! was a 1980s English musical duo formed by members George Michael and Andrew Ridgeley in 1981. They released the song "Last Christmas" in 1984. I just started learning the song today. It's a combination happy/sad/love song and kind of tricky to sing! I'll keep working on it!
The higher-pitched melody is difficult. I'm working on the entire song. I plan to record the song.
