When critics assail Paul McCartney for his lightweight material, it's songs like "Tomorrow" that they have in mind.I’m glad I don’t belong to those circles because I can’t imagine not appreciating all of the melodic charm, rosewater whimsy and—believe it or not—disguised tension that “Tomorrow” has to offer. Notably more fetching than “Yesterday”, this dreamy, piano-driven cut from 1971’s Wild Life, the debut record by Wings, finds Paul beseeching his dear to stay strong and true as they map out a brighter future together. Backed by airy “ohs” and “ahs” and using an altered vocal that makes him sound younger, Paul projects hope—urgent, infectious hope—even as pain and doubt are plainly evident. “Don’t you let me down tomorrow” doesn’t exactly brim with confidence, and “Holding hands we both abandon sorrow” means there’s sorrow to overcome. And as he sings on my favorite line, “Through the week we beg and steal and borrow / Oh for a chance to get away tomorrow.” It’s a tricky balancing act, cloudy skies and uncertainty mixed with idyllic visions of picnics and “country air”. The glue seems to be those sustained, spacious “ohs” that Paul belts out again and again. They pack both anxiety and optimism. Far from merely twee, “Tomorrow” is fraught emotion made irresistible.
