Immigrant Song" was written during Led Zeppelin's tour of Iceland, Bath and Germany in the summer of 1970. The opening date of this tour took place in Reykjavík, Iceland, which inspired Plant to write the lyrics. He explained in an interview: We weren't being pompous ...

They took the stage together to perform at Live Aid in 1985, welcoming Phil Collins and the Power Station's Tony Thompson on drums. They reunited again in 1988 at the Atlantic Records 40th Anniversary concert with Bonham's son, Jason, taking his turn behind the kit.
