Here's an amusing video [1] that demonstrates this.<p>The first part is a bunch of different famous songs' lyrics sung over the music to the Gilligan's Island theme. The second part is the lyrics to the Gilligan's Island theme sung over the music of different famous songs.<p>Most of the first half is using old folk songs and such, and each is pretty short.<p>The second half, where it is singing Gilligan over other music, has more recent popular songs, such as "The Lion Sleeps Tonight", "Stairway to Heaven", "In-a-Gadda-da-Vida", "Ghost Riders in the Sky", and "Mack the Knife", and they do the full Gilligan's Island lyrics.<p>Of the Gilligan over other songs, probably the best are "Mack the Knife" [2] and "Ghost Rider in the Sky" [3].<p>[1] <a href="https://www.youtube.com/watch?v=adIzx0VXTS0">https://www.youtube.com/watch?v=adIzx0VXTS0</a><p>[2] <a href="https://youtu.be/adIzx0VXTS0?t=645" rel="nofollow">https://youtu.be/adIzx0VXTS0?t=645</a><p>[3] <a href="https://youtu.be/adIzx0VXTS0?t=556" rel="nofollow">https://youtu.be/adIzx0VXTS0?t=556</a>
