This promises to be a brief thread.
Here are your answers, RLRL. Number 1 is the lyric from Seal's "Kiss From A Rose". Number 2 is Bob Seger with the original "We've Got Tonight," from 1978. Kenny Rogers covered the song a few years later in a duet with Sheena Easton. Number 3, "Time After Time" was, indeed, done by Cyndi Lauper.
Hope that helps you.
