Back to the real topic , since you mentioned page , he used this technique on parts of "you shook me" and "Dancing Days" ... Probably he used it in other songs too, but those are the only two I could think of now.
If you need more examples , Pink Floyd "High Hopes" outro solo.
Almost forgot to say , in case you didn't find a slide in a nearby store , you can temporarily use something like a smooth glass bottle , or a beer can.
