Oh, Led Zeppelin, it’s been a long time since I’ve heard this one. Although I feel pretty confident that I’ve heard that opening riff on a commercial or three selling vacations or cars or lite beer, maybe even all three at once. Honestly, and this is embarrassing, but I don’t know that I knew it was you who sang this, Led Zeppelin. Whatever. I’ve made it clear that I’m actually pretty uninformed about music even though this is ostensibly a music blog. I do appreciate it more, though, now that I understand that it’s about you proving you could still rock and that it’s a love letter to the early rock and roll from the ’50s. I think you nailed it on both, Led Zeppelin. It might also be about sex. And I’m sure you nailed it there, too.
