Lever Harp - Level 3 - Digital Download SKU: A0.1198695 By Petula Clark. By Tony Hatch. Arranged by Laurie Peterson. 20th Century,Pop. Score. 5 pages. Laurie Peterson #797773. Published by Laurie Peterson (A0.1198695). This hit song from 1964 and sung by Petula Clark is for intermediate level double strung harp for 22+ strings (minimum G to G). It is in the key of G (with F#s). There are 2 lever changes in the right hand near the end of the song (F-sharp to F-natural and B-natural to Bb) and you're given 4 measures to do them to make them manageable. If you don't have a lever to change to Bb, you can skip it and go to the ending section. I love this song...it's a winner!
