Narrative:

On short final ILS [runway] 22L; boston tower controller was giving a full route ATC clearance to another aircraft on tower frequency. It appears the tower controller was controlling boston clearance; pushback clearances; ground & tower duties all on the tower single frequency. The frequency was congested even at that time of night due to weather problems earlier in the day. If any aircraft on short final needed to transmit a question or ask to verify landing clearance; it would be very difficult. The controller was very busy but appeared to handle the late night rush of traffic. The level of activity required of the single controller was unacceptably high & could easily lead to a human error due to saturation of work.
