This is totally supposed to be "Venus and Mars/RockShow/Jet" but "Too Many People" is a great song too!
McCartney is so underrated. Unpopular opinion: Lennon had, like, three good solo songs. And none of them were called Imagine.
Most of the Wings albums have been remastered and re released (after inexplicably being out of print for years) recently. All of these reissues have many extra tracks. Paul released many non album singles during this time and you can find them on these re releases. Venus and Mars was just released a month or so ago and the bonus cd is very good. Hit singles "Juniors Farm" and "Sally G" are on it as well as an awesome song called "soily" (there is a live version of this on the "Over America" album). In the past couple of years, Paul has reissued McCartney, Ram, Band On The Run, Venus and Mars, Wings Over America, McCartney II and At The Speed Of Sound (my least favorite Wings album). These reissues are awesome.
