For years i've been searching for this music. Any ideas or help would greatly be appreciated! The First clip was used in a tv special in 1993. The second was used in 1989. So any music before then is possible. Both are all synths and electronics. The actual song in the second clip may not include those 'siren' sounds..it's hard to tell.
