To find David Gilmour's *The CBS Promos* (1978) release, you might need to explore dedicated collector forums or Pink Floyd fan communities, as this promo is rare and typically circulated among enthusiasts. The links you've shared point to sites that might have had the content in the past, but if those links are dead, here are a few suggestions:
1. **Discogs**: Keep checking listings on Discogs for updates, as this platform often has new listings from sellers specializing in rare music memorabilia.
2. **Guitars101**: Occasionally, collectors on Guitars101 reshare links or provide new ones in the comments. Checking back periodically or posting your own inquiry could help.
3. **Fan Forums**: Pink Floyd-centric communities or music trading groups often have members who archive rare material and might be able to provide direction on where to locate the promos.
In the meantime, consider joining a Pink Floyd fan group or collector’s network where this type of material is traded among dedicated fans.
