Are you tired of the double rainbow schtick? We really thought we might be (so jaded, so fast!). But this acoustic version of “Double Rainbow: All the Way” starts to really jam around 36 seconds in, and the beginning has something melancholic and appealingly after-school grunge about it. Okay, we’re feeling it. Maybe. Or maybe we’re just entranced by the rapid evolution of viral video to Auto-Tune to remix to remixed remix. To, naturally, acoustic. Not your cup of tea? No worries: There are now 5,290 “double rainbow” results on YouTube.
