Water On Glass was the third single release from Kim's self-titled debut album and reached #11 in the UK singles chart, although the album version is slightly different.
There can't be many songs out there which are about tinnitus, but that's exactly what the lyrics are referring to in Water On Glass. By the way, tinnitus is a medical condition that causes ringing in the ears and is often caused by listening to music with the volume up too loudly - so turn your speakers down!
The previous two singles Kids In America and Chequered Love had both reached the Top 5. Overall, Kim Wilde released 21 singles during the 1980's, two of which were not released in the UK and three of them failing to break into the Top 40.
