Huggy Bear's Long Distance Lovers EP is available along with every other Huggy Bear 7 inch here.
Belreve's "The Sky Is Falling" is available for free download from Slumberland, who are also selling a CD compiling all the band's releases.
Pufftube's awesome, awesome, awesome version of "Boys of Summer" is available on their what I thought would be unlikely to exist myspace page.
Greenhorn's "Through the Thick of It" was included on Mike Lupica's terrific Anti-Static Podcast, which has a similar concept to what I'd hoped to do but is much better executed. (April 9th, 2008 edition, in case you wondering.)
All were 7 inches I had pulled from my collection with intention of posting them. I suppose I needn't had bothered. I did manage to find the below ditty, which legitimately seems to be unavailable elsewhere. (Fingers crossed, fingers crossed.)
The Ampersands "Postcards"
I can't even find too much info on this band other than that they were a four-piece from Australia. This single was one of two they released, both on Harriet Records, a label that is very well regarded among the twee set. From this example, it's easy to hear why: a near perfect two minutes of fey, kissyface pop.
