I'll totally have to cheat today. It took about 5 years of piano lessons in the mid 90s, as well as a couple weeks dicking around on a guitar, to realize I have no musical ability. So, my options here are incredibly limited. But, we'll give it a shot.
"Waitin' On A Sunny Day" has a fairly simple chord progression - C, Am, F, C, G. Just play that over and over again, and you've got "Waitin' On A Sunny Day". Sure, there's a solo in there, and some different chords at the end, and the F chord is kinda hard, but you can kinda sorta strum something that sounds like "Waitin' On A Sunny Day". Just take my word for it, because I won't show you in person.
Do we have any musically inclined people? Can you play any Springsteen songs? Comment below!
