What's got her attention?

Apparently a beat group playing on the roof of Apple Corps in January 1969.They had also caught the attention of a young constable who didn't seem to know what to do. (Pictured.) He said they had 30 complaints about the noise, but was being given the runaround by Apple staff. ("The roof is delicate, and wouldn't support your weight.")  Meanwhile the Wee City Rollers played on. (Pictured.)
