Band Aid consisted of a collection of individual artists and members of various bands; it wasn't a group of bands. However, many members came from existing bands. It is difficult to say precisely how many bands were represented, as some artists were solo acts.
While the reference mentions that the 37 performers at that point claimed 23 Number 1 singles between them, it is not explicitly stated how many distinct bands contributed members to Band-Aid. However, the reference does give a list of bands who's members were in Band-Aid.
Here's a list of bands whose members were part of Band Aid, according to the reference:
- The Police (Sting)
- Wham! (George Michael)
- The Jam (Paul Weller)
- Culture Club
- Spandau Ballet
- Duran Duran
- Boomtown Rats
- Status Quo
Therefore, at least eight bands were represented in Band-Aid. Other artists may have been from other bands not listed in the given reference.
