When I was a kid, every so often an old tune would be re-released and become a hit. I remember Bill Haley and the Comets, Rock Around the Clock being on Top of the Pops and looking like something from a different age. Today I found out that Song 2 and Firestarter are 20 years old in 2017. 20! Do you remember the re-released Leader of the Pack being a hit in the 70s? Wannabe was 20 last year – making the Spice Girls the modern equivalent of the Shangri Las, or the Ronettes to today’s teenagers.
