The band i just left played a lot of 60s and 70s tunes. The BL wanted to add some new music to the set list for the younger people, so we added New Years Day. Always got a laugh when we rehearsed that tune.
Assuming you mean the U2 song, that came out in 1983. If the "younger" people your BL added it for are in their 50s, then you're good!
The truth is, no matter what your set list consists of, being a cover band is difficult these days. It's so hard to find the perfect combo of songs people will like based on the market and demographics.
