"Future Perfect" by The Spongetones.
I'm prejudiced,though; it's about me and my husband, who co-wrote the song.
-- I would be seriously remiss if I didn't add something in praise of those long-running powerpop gods.
In that case, from their 2000 album Odd Fellows, please enjoy The Spongetone's spectacular cover of Sir Paul McCartney's "On the Wings of a Nightingale" which can be downloaded here.
The song itself -- and I've never been able to determine exactly when Paul wrote it -- was a minor hit for the Everly Brothers on their wonderful 80s comeback album EB 84. The track was produced by Dave Edmunds and was very much in his vein, with lots of massed acoustic guitars. The Spongetones, however, redid the song a la vintage Merseybeat guitar rock, sounding as it might have if the Fab Four had had a go at it back in the day. As you'll hear, they did an absolutely brilliant job-- the basic track recalls the Fabs circa '64 or '65, but with a lovely recreation of George Harrison's All Things Must Pass lead guitar stylings on top. I think it's a knockout.
Oh, and you can download Sir Paul's quite lovely stripped down original solo demo of the song here.
As always, if the clips have expired by the time you get to them, e-mail and I'll send you the mp3s.
