Happy birthday, dad.
And face it, anti-Phil crowd, if it weren't for Mr. Collins Genesis would have had a nasty disbandment right after "The Lamb" tour, or go on with an expensive shit-tier vocalist. Perhaps without Collins I don't even know if the band would have survived after "Nursery Cryme," and we wouldn't have such fantastic lore like 'Supper's Ready' be the incredible piece that it is. Peter was the prose, Steve was the technique, Mike was the ink, Tony was the mind, and Phil was the glue.
On the other hand, Genesis would have remained a cult band without Phil. Short-lived and cerebral, they might have been the Velvet Underground of prog. They would still be the most circlejerked British prog outfit on 8chan, but for entirely different reasons. American Psycho would've been a slightly different story, in place of Phil Collins and Genesis would probably be someone like Lionel Ritchie and there'd be more focus on Huey Lewis and the News. Randy Newman and Sarah McLachlan would have took the Best Original Song Oscar in 2000 for "When She Loved Me," because not only there wouldn't be Phil Collins, there also wouldn't be Disney's "Tarzan" (1999). Maybe "Blame Canada" would have taken it on behalf of South Park, but then we wouldn't have the classic song "You'll Be in... Me."
And possibly the greatest outcome that would come if Phil Collins were never born, there would be no Undertale. Undertale's emotional core wouldn't be possible without the impact Collins made on Genesis. If it did exist, it would have a completely different story, and there'd be no meaning to the trash memes it spawned, so they wouldn't even be popular memes to begin with. The Internet might have been better off.
So be grateful that humanity has been blessed with Phil Collins sixty-seven years ago today. There's a lot of garbage that came with it but there's double the amount of gold behind it.
