Don't have the WB promo, but I DO have the yellow label "Mad Mix" 12" single, which I found at a record show in the early '90s for two or three bucks.
Listen to him in 2010, still so incredibly funky! Kills the version on the 20Ten LP. Great insight into the way he rehearsed his band, checking that everyone knows the parts and changes, him messing around on guitar and joking with the vocals. It's so good...
There's two versions on the yellow-label 12". The regular extended version and the 10:44 "Mad Mix", which sounds like a DJ re-edit, with added effects and someone trying to sound like Prince adding vocals.
Not the best needledrop on that. Vinyl noise + the surprise ending was completely cut off. The version on the Singles Collection Volume One boot sounds great Mountains [extended version]
Like many artists Melissa Etheridge is in the midst of doing short daily sets during the current worldwide lockdown/stay-at-homes. Yesterday she paid a little tribute to Prince with this Kiss Me/Kiss medley. Fun.
Sirius XM just launched a limited time channel devoted to Prince (which they also did in 2016 shortly after his passing). It's on channel 30. For those who aren't subscribers, Sirius is available to stream for free through May 31 including on their website and app. It replaces the Billy Joel Channel that was on Channel 30 for the month of April. So, based on that timeline, the dedicated Prince channel may only be around for a month. Experience Prince’s hits, never-before-heard radio show & more on exclusive channel
