Eurovision and second conditionals

Now, here you have a grammar pill today! As you already know, second conditionals are used in English to talk about imaginary or hypothetical situations. Listen to Space Man, Sam Ryder's song representing United Kingdom at the Eurovision Song Contest 2022. 

1. How many second conditionals can you find? Take the very first sentence of the song as an example. 

2. Can you explain the structure?

3. Let's talk about it... What is the meaning of the conditionals, of the whole song? What would it happen if YOU were an astronaut? And, could you imagine another paragraph for the song?

This song makes me think of Elton John's Your Song... do you guess why? Again, second conditionals as main structure... a classic.
