Columbia records put out some great 45s in the 60s that are not easy to locate. Here is one by the Illusions that has some great garage organ and pounding drums. This was a 45 I had been trying to find for quite awhile and I picked it up at an amazing garage sale in Durham, NC last year. My friend Jason and I were going to Danville, VA to a record store and saw an ad on Craiglist so we stopped by on our way out of town. This guy was moving and had tons of 60's garage 45s he was selling at extremely reasonable prices. I ended up not only spending a bunch of $ that day with my friend Jason, but I called the guy up and went back later in the week.
