Help me to identify two originals. I have remakes only.

[vinylgeorge]

I`m trying to identify two (probably) British songs from the sixties. I would like to know the original titles and who sang them. However, all I have to go on are only Czech cover versions - (in the Czech language) which you can hear on:

(ONLY SONGS No.1 and No.3, No.2 and 4. are clear already)

I think only the melody (tune) is a clue (guidepost) because the Czech lyrics may have nothing to do with the original English lyrics mostly.
They mostly "stole" the melody (they recorded it from an outland radio station) and added Czech words....

Could you help me please? Or can you advise me where to turn with my problem?
I am unsuccessful to this time.
