What about?: Number 1 (whatever that is these days) at the moment, 10 years ago today, 20 years ago, 30 ... right back to the 50s/60s?Upbeat pop from different eras, such as Dancing Queen-Abba, Galway Girl -Ed Sheeran, Walking on Sunshine-Katrina and the Waves, One more time - Daft Punk, Shiney Happy People-REM, etc.
Obviously a bit of poetic licence as to what you play (no Macarthurs Park ??)
That could be a repeatable format as each home game is a couple of weeks apart so can be varied plus would throw up some great old tunes and some interesting oddments.
You could do a feature on the music in the programme too, commenting onwhat will be played plus what else was in the charts that week?
Either start from modern and work back or vicky verky??
