It's this song: https://www.youtube.com/watch?v=0IUV-QxwlRM To "rave" is a speak or act enthusiastically. In the song, the singer is telling the girl he loves to tell him, to "rave on", how much she loves him.

Thank you to clear it out.

Only in Britain though.

Thanks Mick, very appreciated.

These days we might say "bang on"
