Hello to anyone who can help me, and to those who can't

[graag49]

I'm not a photographer like most of you here, but a musician who needs
your advice. I'm building a mini-version of a 60's-era light show to use
as part of my band/solo performances. I want to incorporate 35mm
slide images into this project but I'm having trouble finding a good source
for slides. I have a Kodak Ektagraphic III-E, which should be fine for a
basic projector, so now I need slides to enhance the impact of certain songs. I realize everything is going to digital ( Powerpoint, etc. ) but I
can't afford that route, so I need the "older-style" slides.
Are there any companies or individuals who have categorized galleries
of 35mm slides for sale? ( ie: 60's/70's images, space photos, unusual
"scenics", historical events or personalities, etc.)
If anyone has any advice, please let me know and Many Thanks!

I'm not sure about sources for specific slides, but check ebay for slides.
