Old TV footage, and old EoFF members normally do it for me. But the thing about nostalgia is that it has to be unexpected. Hearing a song from your youth won't normally evoke feelings of nostalgia, because chances are the song has been played once a week on the radio for the past ten years. But if it was a song that you hadn't heard since its initial release, and that you had forgotten even existed, that's going to get you harking back to the good ol' days.
Hi there, Nait.
